How much carbonic acid can be obtained by reacting 2 liters of carbon dioxide with water

How much carbonic acid can be obtained by reacting 2 liters of carbon dioxide with water, if the acid yield is 90% compared to theoretical.

Let’s execute the solution:

According to the condition of the problem, we will write the data:
V = 2 L X g -? W = 90%

СО2 + Н2О = Н2СО3 – compounds, carbonic acid was formed;

We make calculations:
M (CO2) = 44 g / mol;

M (H2CO3) = 62 g / mol.

Proportion:
1 mol of gas at normal level – 22.4 liters;

X mol (CO2) -2 L hence, X mol (CO2) = 1 * 2 / 22.4 = 0.09 mol;

Y (H2CO3) = 0.09 mol since the amount of substances is 1 mol.

Find the mass of acid:
m (H2CO3) = Y * M = 0.09 * 62 = 5.58 g (theoretical weight);

m (H2CO3) = 0.90 * 5.58 = 5.02 g (practical weight).

Answer: obtained carbonic acid weighing 5.02 g
