Find the volume of gas that can be obtained by fusing 230 g of sodium acetate containing 5%

Find the volume of gas that can be obtained by fusing 230 g of sodium acetate containing 5% impurities with sodium hydroxide.

Let’s implement the solution:

In accordance with the condition of the problem, we write down the equation of the process:
CH3COONa + NaOH = CH4 + Na2CO3 – methane is released;

We make calculations:
M (CH3COONa) = 81.9 g / mol;

M (CH4) = 16 g / mol;

m (CH3COONa) = 230 * (1 – 0.5) = 115 g (mass without impurity).

Determine the amount of the original substance:
Y (CH3COONa) = m / M = 115 / 81.9 = 1.4 mol;

Y (CH4) = 1.4 mol since the amount of substances is 1 mol.

Find the volume of the product:
V (CH4) = 1.4 * 22.4 = 31.36 L

Answer: methane produced with a volume of 31.36 liters
