5. Calculate the molar mass of the following compounds,#5.) (NH4)2 SO4
Answer:
The molar mass of (NH4)2SO4 is:
(2 x 14.007) + (4 x 1.008) + 32.06 + (4 x 16.00) = 132.14 g/mol
Where,
N = 14.007 g/mol
H = 1.008 g/mol
S = 32.06 g/mol
O = 16.00 g/mol
So, (NH4)2SO4 has a molar mass of 132.14 g/mol.

10. Calculate the molar mass of ammonium hydrogen phosphate, (NH4)2 HPO4.
✒️MOLAR MASS
[tex]\tt{\huge{\blue{Solution:}}}[/tex]
The problem asks to solve for the molar mass of ammonium hydrogen phosphate, (NH₄)₂HPO₄. To calculate molar mass, we need to add all the atomic masses in the compound. For each element, we multiply the atomic mass of the element by the number of atoms of that element in a compound. We find atomic masses in the periodic table.
Since there are two N atoms, nine H atoms, one P atom, and four O atoms, then the molar mass of ammonium hydrogen phosphate is
molar mass of (NH₄)₂HPO₄ = 2(14.01 g/mol) + 9(1.008 g/mol) + 30.97 g/mol + 4(16.00 g/mol)
[tex]\boxed{\text{molar mass of} \: (\text{NH}_{4})_{2}\text{HPO}_{4} = \text{132.06 g/mol}}[/tex]

22. The atomic number of NH4
Answer:
Atomic number of Nitrogen is 7 and Hydrogen is 1
Answer:
In an ammonium ion (NH+4) ion, there is one nitrogen atom and four hydrogen atoms. Nitrogen has an atomic number of 7 , and hydrogen has an atomic number of 1 , and so the total atomic number of the hydrogens will be 1⋅4=4 . So, there will be a total of 7+4=11 protons.

24. Balance the following NH₃ + H₂ Soi (NH4)₂SOA C ) 2
Answer:
Multiply the
NH3 by 2
.
Explanation:
To balance the below reaction you will need to multiply the NH3 by 2 .2NH3+H2SO4→(NH4)2SO4
Then you will have:
2N to the left and 2N to the right.8H=(2×3) from 2NH3+2 from H2SO4 to the left and 8H=2 4 from (NH4)2SO4 to the right.
SO4 to the left and SO4 to the right.

28. Determine the charges of the underlined elements.1. OH-2. NH4+
Answer:
1. When water ionizes one of the hydrogen atoms absconds with itself and leaves it's electron behind, giving us the hydroxide ion. The extra electron gives hydroxide a net charge of -1. The brackets indicate that this is an ion, charge is denoted at top right.
2. NH4+ has a + charge because it is NH3 that has formed a bond with a H+ using the N lone pair. The whole ion has 1 more proton than it has electrons hence the charge.
