theoretical and percent yield question.?

Question

Tried once got it wrong. only got once attempt left. please help

Consider the following reaction.
SO3(g) + H2O(l) H2SO4(aq)

A chemist allows 60.7 g of SO3 and 11.1 g of H2O to react. When the reaction is finished, the chemist collects 54.2 g of H2SO4. Determine the theoretical yield, and percent yield for the reaction.

_______theoretical yield
________.percent yield

Answer 1

Atomic weights: H = 1, O = 16, S = 32
60.7gSO3 x 1molSO3/80gSO3 = 0.76molSO3
11.1gH2O x 1molH2O/18gH2O = 0.62molH2O
The limiting reagent is H2O, which can produce a maximum of 0.62molH2SO4.
0.62molH2SO4 x 98gH2SO4/1molH2SO4 = 60.4gH2SO4
Percent yield = 54.2gH2SO4/60.4gH2SO4 x 100% = 89.7%
