What is the mass of sorbitol С6Н14О6 formed when 45 g of glucose interacts with hydrogen?

To solve the problem, we write the chemical reaction equation
C6H12O6 + H2 = C6H14O6
In this case, for the formation of 1 mol of sorbitol, 1 mol of glucose is needed, and vice versa. Let’s calculate the amount of glucose contained in 45 grams using the formula n = m / M, where m is the mass of glucose, M is the molar mass of a glucose molecule (180 g / mol). Then the amount of glucose n is 45/180 = 0.25 mol
According to the equation n sorbitol = n glucose = 0.25 mol, then m sorbitol is 0.25 mol * 182 g / mol = 45.5 g
Answer: 45.5 g of sorbitol is formed
