In what mass of acetic acid the number of carbon atoms is the same as 32 g of calcium carbide.

1. Let’s calculate the chemical amount of calcium carbide:

n (CaC2) = m (CaC2): M (CaC2);

M (CaC2) = 40 + 2 * 16 = 72 g / mol;

n (CaC2) = 32: 72 = 0.4444 mol;

2.determine the number of carbon atoms in the carbide:

n (C) = n (CaC2) * 2 = 0.4444 * 2 = 0.8888 mol;

3. find the amount of acetic acid:

n (CH3COOH) = n (C): 2 = 0.4444 mol;

4.Calculate the mass of the acid:

m (CH3COOH) = n (CH3COOH) * M (CH3COOH);

M (CH3COOH) = 12 + 3 + 12 + 32 + 1 = 60 g / mol;

m (CH3COOH) = 0.4444 * 60 = 26.66 g.

Answer: 26.66 g.
