When 240 g of 10% NaOH solution interacted with carbon dioxide, a medium salt was formed. Calculate the volume of the gas that has reacted.
2NAOH + CO2 = NA2CO3 + H2O
1.m (NAOH substance) = W * m (NAOH solution) = 0.1 * 240 = 24 grams.
2.n (NaOH) = m / M = 24/40 = 0.6 mol.
3. For CCR: n (NaOH): n (CO2) = 1: 2 = n (cO2) = 0.3 mol.
4.V (CO2) = n * Vm = 0.3 * 22.4 = 6.72 liters.
Answer: 6.72 liters.
