2. Calculate the mass percentage composition of acetone which has the chemical formula C3H6O.
The mass % of any element = [(no, of the element atoms x atomic mass of the element) / molar mass of the compound] x 100. Thus the mass % of O = (Atomic mass of O / molar mass of acetone) x 100 = [(15.999 g/mol) / (58.08 g/mol)] is equal to 7.6 %. hope it helps
3. Which of the following is NOT a true statement concerning empirical and molecular formulas? a. The empirical formula of a compound can be triple its molecular formula. b. Several compounds can have the same empirical formula, but have different molecular formulas. c. The molecular formula of a compound can be the same as its empirical formula. d. The molecular formula of a compound can be some whole-number multiple of its empirical formula.
Answer:
BExplanation:
An empirical formula is the simplest ratio of atoms in a formula unit. The true ratio of atoms in a formula unit is called the molecular formula, also with the true molecular mass of a chemical formula. Empirical formulas represent the lowest ratio of coefficients in a chemical formula.4. empirical formula of C6H6

Description
Therapeutic Epinephrine is the synthetic form of the naturally occurring sympathomimetic amine with vasoconstricting, intraocular pressure-reducing, and bronchodilating activities. By stimulating vascular alpha-adrenergic receptors, epinephrine causes vasoconstriction, thereby increasing vascular resistance and blood pressure. When administered in the conjunctiva, this agent binds to alpha-adrenergic receptors in the iris sphincter muscle, resulting in vasoconstriction, a decrease in the production of aqueous humor, and a lowering of intraocular pressure. Through its beta1 receptor-stimulating actions, epinephrine increases the force and rate of myocardial contraction and relaxes bronchial smooth muscle, resulting in bronchodilation.
NCI Thesaurus (NCIt)
Epinephrine appears as white to nearly-white microcrystalline powder or granules. Odorless. Melting point 211-212°C. Aqueous solutions are slightly alkaline. Slightly bitter, numbing taste.
CAMEO Chemicals
Epinephrine, also known as adrenaline, is a hormone and neurotransmitter and produced by the adrenal glands that can also be used as a drug due to its various important functions. Though it has long been used in the treatment of hypersensitivity reactions, epinephrine in the auto-injector form (EpiPen) has been available since 1987 in the USA.Many new products/biosimilars and dosage routes have been approved under various names over the last several decades,.On August 16, 2018, Teva Pharmaceuticals USA gained approval to market its generic epinephrine auto-injector in 0.3 mg and 0.15 mg strengths.Dosage delivery routes for epinephrine include intravenous, inhalation, nebulization, intramuscular injection, and subcutaneous injection.In general, the most common uses of parenteral epinephrine are to relieve respiratory distress due to bronchospasm, to provide rapid relief of hypersensitivity (anaphylactic or anaphylactoid) reactions to drugs, animal serums and other allergens, and to prolong the action of infiltration anesthetics. In addition to the above functions, epinephrine is the primary drug administered during cardiopulmonary resuscitation (CPR) to reverse cardiac arrest.It can be used in severe cases of croup.

8. what is empirical formula?
Answer:
a formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.
Answer:
the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of sulfur monoxide, or SO, would simply be SO, as is the empirical formula of disulfur dioxide, S₂O₂.
9. Differentiate molecular formula and empirical formula
The empirical formula of a compound gives the simplest ratio of the number of different atoms present, whereas the molecular formula gives the actual number of each different atom present in a molecule. If the formula is simplified then it is an empirical formula.
10. is the empirical formula the same as molecular formula?
Answer:
Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.
11. A compound has an empirical formula of C2H5. What is true about this empirical formula?
C₂H₅ is alkyl and the mole ratio of the elements C and H is 2: 5
Further explanationAlkanes are saturated hydrocarbons with all carbon bonds being single bonds
General formula:
CnH2n+2A compound has an empirical formula of C₂H₅
The empirical formula is the smallest comparison of atoms of compound forming elements.
Also shows the mole ratio of the molecular elements
There are 2 things that might be shown from this empirical formula
1. The mole ratio of element C and element H is 2: 5
2. C₂H₅ is an alkyl, that is, an alkane that loses one H atom.
