23. QUESTION 13 Maria wants to know the mass of her science laboratory module, what laboratory apparatus should she use? a. Thermometer b. Platform balance c. Graduated cylinder d. Flask


Answer:

B.

Explanation:

A platform balance, also known as a platform scale, is a type of weighing apparatus used to measure the weight or mass of an object. It consists of a flat platform or surface where the object is placed and a measuring device, typically a spring or a strain gauge, that measures the amount of force applied to the platform. The measuring device is connected to a display that shows the weight of the object.

Platform balances can come in various sizes, with larger ones often used in industries and smaller ones used in laboratories or homes. They can be manually operated or have digital displays, and some models can be connected to a computer or other device for data collection and analysis.

Platform balances are commonly used for a wide range of applications, including weighing materials for production, measuring ingredients in recipes, and weighing items for shipping or mailing. They are a reliable and accurate way to measure the weight or mass of an object, and they are an essential tool for many businesses, laboratories, and individuals.


24. A series of dilute NaCl solutions is prepared, starting with an initial stock solution of 0.100 M NaCl. Solution A is prepared by pipetting 10 mL of the stock solution into a 250-mL volumetric flask and diluting to volume. Solution B is prepared by pipetting 25 mL of solution A into a 100-mL volumetric flask and diluting to volume. Solution C is prepared by pipetting 20 mL of solution B into a 500-mL volumetric flask and diluting to volume. What is the molar concentration of NaCl in solutions A, B, and C?


SOLUTION:For Solution A

Step 1: List the given values.

[tex]\begin{aligned} & M_{\text{i}} = 0.100 \: M \\ & V_{\text{i}} = \text{10 mL} \\ & V_{\text{f}} = \text{250 mL} \end{aligned}[/tex]

Step 2: Calculate the molar concentration of Solution A.

[tex]\begin{aligned} M_{\text{f}} & = \frac{M_{\text{i}}V_{\text{i}}}{V_{\text{f}}} \\ & = \frac{(0.100 \: M)(\text{10 mL})}{\text{250 mL}} \\ & = \boxed{4.00 \times 10^{-3} \: M} \end{aligned}[/tex]

Hence, the molar concentration of Solution A is 4.00 × 10⁻³ M.

For Solution B

Step 1: List the given values.

[tex]\begin{aligned} & M_{\text{i}} = 4.00 \times 10^{-3} \: M \\ & V_{\text{i}} = \text{25 mL} \\ & V_{\text{f}} = \text{100 mL} \end{aligned}[/tex]

Step 2: Calculate the molar concentration of Solution B.

[tex]\begin{aligned} M_{\text{f}} & = \frac{M_{\text{i}}V_{\text{i}}}{V_{\text{f}}} \\ & = \frac{(4 \times 10^{-3} \: M)(\text{25 mL})}{\text{100 mL}} \\ & = \boxed{1.00 \times 10^{-3} \: M} \end{aligned}[/tex]

Hence, the molar concentration of Solution B is 1.00 × 10⁻³ M.

For Solution C

Step 1: List the given values.

[tex]\begin{aligned} & M_{\text{i}} = 1.00 \times 10^{-3} \: M \\ & V_{\text{i}} = \text{20 mL} \\ & V_{\text{f}} = \text{500 mL} \end{aligned}[/tex]

Step 2: Calculate the molar concentration of Solution C.

[tex]\begin{aligned} M_{\text{f}} & = \frac{M_{\text{i}}V_{\text{i}}}{V_{\text{f}}} \\ & = \frac{(1.00 \times 10^{-3} \: M)(\text{20 mL})}{\text{500 mL}} \\ & = \boxed{4.00 \times 10^{-5} \: M} \end{aligned}[/tex]

Hence, the molar concentration of Solution C is 4.00 × 10⁻⁵ M.
