Calculate the mass of sodium phenolate, which can be obtained by reacting 4.7 g of phenol with sodium hydroxide solution.

To solve the problem, we compose the equation according to the condition of the problem:
1. C6H5OH + NaOH = C6H5ONa + H2O – exchange, sodium phenolate was formed;
2. We make calculations by the formulas:
M (C6H5OH) = 94 g / mol.
M (C6H5ONa) = 115.9 g / mol.
Y (C6H5OH) = m / M = 4.7 / 94 = 0.05 mol.
Y (C6H5ONa) = 0.05 mol since the amount of substances is 1 mol.
3. Find the mass of salt:
m (C6H5ONa) = Y * M = 0.05 * 115.9 = 5.79 g.
Answer: an organic sodium phenolate salt with a mass of 5.79 g was obtained.
