Calculate the mass of nitric acid that will result from the reaction of 3 tons of water with nitric oxide (∨).

Nitric oxide (V) is a colorless crystalline substance. It dissolves well in water with the formation of a strong acid – nitric. Reaction equation:

N2O5 + H2O = 2 HNO3

For the convenience of calculations, we will convert the mass of water from tons to grams.

m (H2O) = 3 t = 3,000,000 g = 3 * 10 ^ 6 g.

Molar masses of substances:

M (H2O) = 18 g / mol;

M (HNO3) = 63 g / mol.

Let’s make a proportion according to the reaction equation:

3 * 10 ^ 6 g H2O corresponds to X g HNO3, as

18 g / mol H2O corresponds to 2 * 63 g / mol HNO3.

X = (3 * 10 ^ 6 * 2 * 63) / 18 = 21 * 10 ^ 6 g = 21 tons of nitric oxide (V).

Answer: the mass of nitric acid is 21 tons.
