Question

part 1 of 2
zinc chloride (zncl₂) is 52.02% chlorine by mass. what mass of chlorine is contained in 62.1 g of zncl₂?
answer in units of g.

1. 35.7898
2. 41.72
3. 50.2513
4. 37.8185
5. 42.1882
6. 34.3332
7. 43.1246
8. 36.8822
9. 32.3044
10. 27.9868

Explanation:

Step1: Understand the formula for mass percentage

The mass of a component in a compound can be calculated using the formula: \( \text{Mass of component} = \text{Mass of compound} \times \text{Mass percentage of component} \)

Step2: Substitute the given values

We know the mass of \( \text{ZnCl}_2 \) is \( 62.1 \, \text{g} \) and the mass percentage of chlorine is \( 52.02\% \) or \( 0.5202 \) in decimal form.

So, \( \text{Mass of chlorine} = 62.1 \, \text{g} \times 0.5202 \)

Step3: Calculate the result

\( 62.1 \times 0.5202 = 32.30442 \approx 32.3044 \) (rounded to four decimal places)

Answer:

1. 32.3044
