A. Find the molar mass for benzene and chlorobenzene. b. If 45.6 g of benzene reacts, how many grams of chlorobenzene can be produced?

Step 1: convert grams of benzene to moles of benzene

Step 2: use the molar ratio to find the moles of chlorobenzene that can be produced.

Step 3: convert moles of chlorobenzene to grams of
chlorobenzene

C. If the actual yield is 63.7 g chlorobenzene, calculate the percent yield

explanation:

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
