..happy to take a two question hit, but I need a,b,and c please.A sample of a mixture containing an unknown hydrocarbon and some nitrogen dioxide, NO2, had a totalmass of 31.25 grams. The mixture was analyzed using combustion analysis, producing 78.44 g of carbondioxide, CO2, and 32.12 g of water, H2O.a) Calculate the empirical formula of the hydrocarbon. b) The molar mass of the compound was found to be 252.48 g/mol. What is the molecular formula of thehydrocarbon? c) What percentage (by mass) of the original sample was the hydrocarbon?

..happy to take a two question hit, but I need a,b,and c please.

A sample of a mixture containing an unknown hydrocarbon and some nitrogen dioxide, NO2, had a total
mass of 31.25 grams. The mixture was analyzed using combustion analysis, producing 78.44 g of carbon
dioxide, CO2, and 32.12 g of water, H2O.
a) Calculate the empirical formula of the hydrocarbon.

b) The molar mass of the compound was found to be 252.48 g/mol. What is the molecular formula of the
hydrocarbon?

c) What percentage (by mass) of the original sample was the hydrocarbon?
