0.333 g of a hydrocarbon (C_xH_y) was analyzed by combustion analysis and 1.009 g of CO₂ (MM = 44.01 g/mol) and 0.516 g of H₂O (MM = 18.02 g/mol). How many moles of hydrogen were in the 0.333 g sample?

Expert Solution

Step 1

Mole concept:

The number of molecules or atoms present in the one mole of the substance is equal to the Avogadro number. The value of the Avogadro number is 6.022x10²³. The mass of one mole of a substance is known as the molar mass.
