¨ To calculate the mass of 3.2 moles of ammonia (NH3) gas, we need to use its molar mass.
¨ Molar mass of NH3 = (1 x atomic mass of N) + (3 x atomic mass of H) = (1 x 14.01) + (3 x 1.01) = 17.03 g/mol
¨ Now, we can use the mole-to-mass conversion formula:
¨ Mass = number of moles x molar mass
¨ Substituting the given values:
¨ Mass = 3.2 mol x 17.03 g/mol = 54.496 g
