What volume of carbon dioxide will be released during the interaction of 150 g of a 20% solution of acetic acid and CaCO3?
March 11, 2021 | education
| 1. Let’s compose the equation of interaction of acetic acid and calcium carbonate:
2CH3COOH + CaCO3 → (CH3COO) 2Ca + H2O + CO2 ↑;
2.Calculate the mass of acetic acid:
m (CH3COOH) = w (CH3COOH) * m (solution) = 0.2 * 150 = 30 g;
3. find the chemical amount of acetic acid:
n (CH3COOH) = m (CH3COOH): M (CH3COOH);
M (CH3COOH) = 12 + 3 + 12 + 32 + 1 = 60 g / mol;
n (CH3COOH) = 30: 60 = 0.5 mol;
4.determine the amount of carbon dioxide:
n (CO2) = n (CH3COOH): 2 = 0.5: 2 = 0.25 mol;
5. find the volume of carbon dioxide:
V (CO2) = n (CO2) * Vm = 0.25 * 22.4 = 5.6 liters.
Answer: 5.6 liters.
