A dry-cleaning solvent (molecular weight = 146.99 g/mol) that contains C, H, and Cl is suspected to be a cancer-causing agent. When a 0.112 g sample was studied by combustion analysis, 0.201 g of CO2 and 0.0272 g of H2O formed.
How many moles of each of the following were in the original sample?
C mol?
H mol?
Cl mol?
What is the molecular formula? (Type your answer using the format H2O for H2O.)
