    If 13.4 grams of nitrogen gas reacts we'll produce 16.3 grams of ammonia

    Explanation:

    Step 1: Data given

    Mass of nitrogen gas (N2) = 13.4 grams

    Molar mass of N2 = 28 g/mol

    Molar mass of NH3 = 17.03 g/mol

    Step 2: The balanced equation

    N2 + 3H2 → 2NH3

    Step 3: Calculate moles of N2

    Moles N2 = Mass N2 / molar mass N2

    Moles N2 = 13.4 grams / 28.00 g/mol

    Moles N2 = 0.479 moles

    Step 4: Calculate moles of NH3

    For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

    For 0.479 moles N2 we'll produce 2*0.479 = 0.958 moles

    Step 5: Calculate mass of NH3

    Mass of NH3 = moles NH3 * molar mass NH3

    Mass NH3 = 0.958 moles * 17.03 g/mol

    Mass NH3 = 16.3 grams

    If 13.4 grams of nitrogen gas reacts we'll produce 16.3 grams of ammonia
