Zinc chloride (ZnCl2) is 52.02% chlorine by
mass. What mass of chlorine is contained in
85.0 g of ZnCl2?
Answer in units of g
85.0 x 0.052.02 = ?
To find the mass of chlorine contained in 85.0 grams of ZnCl2, we can start by calculating the mass of chlorine in 100 grams of ZnCl2 since we know that it is 52.02% chlorine by mass.
Step 1: Calculate the mass of chlorine in 100 grams of ZnCl2
Mass of chlorine = (52.02/100) x 100 grams = 52.02 grams
Step 2: Calculate the mass of chlorine in 1 gram of ZnCl2
Mass of chlorine in 1 gram = 52.02 grams/100 grams = 0.5202 grams
Step 3: Calculate the mass of chlorine in 85.0 grams of ZnCl2
Mass of chlorine = 0.5202 grams x 85.0 grams = 44.17 grams
Therefore, the mass of chlorine contained in 85.0 grams of ZnCl2 is 44.17 grams.
