What is the mass of nitric oxide (IV) with a volume of 11.2 liters?

1. With a known volume, we find the chemical amount through the normal volume:

n (NO2) = V (N2): Vm;

n (NO2) = 11.2: 22.4 = 0.5 mol;

2.Calculate the mass of nitrogen oxide by the formula:

m (NO2) = n (NO2) * M (NO2);

M (NO2) = 14 + 2 * 16 = 46 g / mol;

m (NO2) = 0.5 * 46 = 23 g.

Answer: 23 g.
