How many grams of sodium acetane can be obtained by reacting 30 acetic acid with sodium hydroken, if the practical product yield is 60%.

1. According to the condition of the problem, we compose the equation:
CH3COOH + NaOH = CH3COONa + H2O – exchange process, sodium acetate was obtained;
2. Let’s make the calculations:
M (CH3COOH) = 60 g / mol;
M (CH3COONa) = 78.98 g / mol.
3. Determine the amount of mol of acetic acid, if the mass is known:
Y (CH3COOH) = m / M = 30/60 = 0.5 mol;
Y (CH3COONa) = 0.5 mol since the amount of these substances according to the equation is 1 mol.
4. Find the theoretical mass of salt – CH3COONa:
m (CH3COONa) = Y * M = 0.5 * 78.98 = 39.49 g.
We calculate the practical weight by the formula:
W = m (practical) * m (theoretical) * 100;
m (practical) = 0.60 * 39.49 = 23.69 g.
Answer: the mass of the organic sodium acetate salt is 23.69 g.
