Calculate the mass of gluconic acid that can be obtained from glucose with an amount of 2 mol.

Let’s carry out the solution, write down the equation:
С6Н12О6 + Cu (OH) 2 = HO – CH2 – (CHOH) 4 – COOH + Cu2O + 2H2O – the oxidation of glucose with copper hydroxide occurs when heated, gluconic acid is released;
Let’s calculate the molar masses of substances:
M (C6H12O6) = 180 g / mol;
M (gluconic acid) = 196 g / mol.
Let’s make the proportion:
2 mol (C6H12O6) – X mol (glucon. To-ta);
1 mol -1 mol from here, Y (glucon. To-ta) = 2 mol.
We find the mass of gluconic acid by the formula:
m (glucon.k-ta) = Y * M = 2 * 196 = 392 g.
Answer: the mass of gluconic acid is 392 g.
