The percent composition of an unknown hydrocarbon is 92.24%

The percent composition of an unknown hydrocarbon is 92.24% Carbon and 7.76% Hydrogen. This hydrocarbon has a molar mass of 78.12 g/mol. When the hydrocarbon reacts with bromine (Br2), Bromobenzene (C6H5Br) and hydrobromic acid are obtained. a. Determine the empirical formula for unknown hydrocarbonb. Determine the molecular formula for the unknown hydrocarbonc. How many grams of bromobenze is produced when 30.0g of the hydrocarbon and 65.0g of bromine react?d. What is the limiting reagent in this reaction?e. What is the percent yield of bromobenze if the actual yield of bromobenzene is 42.3 (based on the conditions above)?Thanks!!!
