How many grams of magnesium acetate can be formed when 12g of magnesium reacts with acetic acid?

Let’s implement the solution:

According to the condition of the problem, we write down the equation of the process:
m = 12 g X g -?

2СН3СООН + Mg = (CH3COO) 2Mg + H2 – substitutions, magnesium acetate is formed;

Calculations:
M (Mg) = 24.3 g / mol;

M (magnesium acetate) = 116.3 g / mol;

Y (Mg) = m / M = 12 / 24.3 = 0.5 mol;

Y (magnesium acetate) = 0.5 mol since the amount of substances is 1 mol.

Find the mass of salt:
m (magnesium acetate) = 0.5 * 116.3 = 58.15 g

Answer: The mass of magnesium acetate is 58.15 g
