Give the name for the acid with the formula H3PO4 .
The characteristic odor of pineapple is due to ethyl butyrate. Combustion of 2.78 mg of ethyl butyrate yields 6.32 g of CO2 and 2.58 g of H20. The property of the compound suggest that the molar mass should be between 100 and 150g/mol. What is the molecular formula?
