1026 g of sucrose on hydrolysis gives how many mole(s) of glucose? (Atomic wt : C = 12 u, H = lu, O = 16 u)

Answer

C

Explanation

The molecular weight of sucrose `C_12H_22O_(11)` is `12 xx 12 + 22 xx 1 + 11 xx 16 = 342` g/ mol. Thus, 342 g of sucrose corresponds to 1 mole.
`therefore 1026` g of sucrose corresponds to `1026/342 =3` moles. 1 mole of sucrose on
hydrolysis gives 1 mole of glucose and 1 mole of fructose. `therefore` 3 moles of sucrose gives 3 moles of glucose.
