Question

Megan wanted to make some calcium chloride (CaCl2) for an experiment. She knew that for every 40 g of calcium there would be 71 g of chlorine. Megan only used 20 g of calcium. Calculate how much chlorine would be in the compound.​

Answer 1

35.5 g of chlorine would be in the compound

Step-by-step explanation:

using the mole concept

first write down your balanced chemical equation

CaCl2_____Ca +Cl2

then if 40g of Ca____ 71 g of cl

so 20g of Ca_____Xg of cl

cross multiplying we have

X= (20 *71)/40 = 35.5g
