Question

11) How many grams of NH, can you make if you use 23 moles of nitrogen gas?

Answer 1

782g

Explanation:

Given parameters:

Number of moles of N₂ = 23moles

Unknown:

Mass of NH₃ = ?

Solution:

We first obtain the balanced chemical equation for this reaction;

    N₂   +    3H₂   →   2NH₃

From the equation we see that;

     1 mole of N₂ produced 2 moles of ammonia

    23 mole of N₂ will yield 2 x 23 = 46moles of ammonia

Now ;

mass of ammonia = number of moles x molar mass

Molar mass of NH₃ = 14 + 3(1) = 17g/mol

 Mass of ammonia = 46 x 17 = 782g
