1026 g of sucrose on hydrolysis gives______mole(s) of glucose.
(Atomic wt: C = 12 u,H = lu, O = 16 u)

Answer

3

Explanation

The molecular weight of sucrose `C_12H_22 O_(11)` is `12 xx 12 + 22 xx 1 + 11 xx 16 = 342`g/ mol
Thus, 342 g of sucrose corresponds to lmole.
`therefore 1026g` 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.
