Fluorine gas can react with ammonia gas to produce dinitrogen tetrafluoride gas and hydrogen fluoride gas. This reaction is described by the following balanced equation:

Question

5 F2 (g) + 2 NH3 (g) N2F4 (g) + 6 HF (g)

What mass of hydrogen fluoride gas is produced from 135 g of ammonia gas assuming that there is an ample amount of fluorine gas present for the reaction to be completed?

Answer 1

mols NH3 = grams/molar mass
Convert mols NH3 to mols HF using the coefficients in the balanced equation.
Convert mols HF to grams HF. g = mols x molar mass.
