Question

What is the mass of reactants in the following equation? N2 + 3H2 ----> 2NH3 Question 3 options: 34.05 amu 31.03 amu 30.02 amu 15.01 amu

Answer 1

34.06amu

Step-by-step explanation:

The reaction expression is given as:

N₂ + 3H₂ → 2NH₃

We are to find the mass of reactants in the equation given;

Here:

Mass of reactants = 2(atomic mass of N) + 3[ 2 x atomic mass of H]

Atomic mass of N = 14.0067amu

Atomic mass of H = 1.008amu

Mass of reactants = 2(14.0067) + 3(2 x 1.008) = 34.06amu
