Sucrose is easily destroyed by acid to form glucose and fructose (C12H22O11 + H2O = C6H12O6 (glucose) + C6H12O6 (fructose)). How many grams of glucose and fructose can be obtained from 300g of sugar?

According to the condition of the problem, we compose the equation:
С12Н22О11 + Н2О = С6Н12О6 (glucose) + С6Н12О6 (fructose) – sucrose hydrolysis occurs in the presence of sulfuric acid, glucose and fructose are released;
We make calculations using the formulas:
M (C12H22O11) = 222 g / mol;
M (C6H12O6) = 180 g / mol.
Determine the amount of mol of sucrose:
Y (C12H22O11) = m / M = 300/222 = 1.35 mol;
Y (C6H12O6) = 1.35 mol, since according to the equation the amount of sucrose, glucose and fructose is equal to 1 mol.
Let’s calculate the mass of glucose, fructose:
m (C6H12O6) = Y * M = 1.35 * 180 = 243 g.
Answer: the mass of glucose, fructose is 243 g.
