| Let’s implement the solution:

1. By the condition of the problem, it is known:

m = 180 g. X g. -?

SO3 + H2O = H2SO4 – compounds, sulfuric acid was obtained;

1 mol 1 mol.

2. Calculation:

M (H2O) = 18 g / mol;

M (H2SO4) = 98 g / mol.

3. Determine the amount of the original substance, if the mass is known:

Y (H2O) = m / M = 180/18 = 10 mol;

Y (H2SO4) = 10 mol since the amount of these substances according to the equation is 1 mol.

4. Find the mass of acid:

m (H2SO4) = Y * M = 10 * 98 = 980 g.

Answer: sulfuric acid with a mass of 980 g was formed.
