The percent yield is determined by dividing the theoretical yield by the percent

yield.

The theoretical yield must be determined relative to the excess reactant.

Which of the following is the empirical formula of $$C_3H_4O_3$$  

A sample was identified to have an empirical formula of $$C_5H_{10}$$   Which of the following is the molecular formula if it’s molecular mass is thrice that of its empirical formula?

Polymers are large molecules composed of simple units repeated many times. Thus, they often have relatively simple empirical formulas. An example of a polymer is Lucite (Plexiglas), which is made of 59.9% C, and 8.06% H. What is the mass of carbon in 100.00 g of a sample of Plexiglas?

What is the percent yield of an unknown substance if its actual yield id 58.6 g, and its theoretical yield is 62.5 g?

What is the actual yield if a substance's percent yield is 89.66 %, and it's theoretical yield is 55.46 g?

What is the volume of 53.6 moles of a gas if its temperature is 65.35 K, in a room where the pressure is 2.5 atm? (R = 8.314 J.K^-1*mol^-1)

Determine the empirical formula for a compound with the following percent composition: 15.8% carbon and 84.2% sulfur

(molar masses: C = 12.011 g/mol, S = 32.065 g/mol)
