Find the percentage composition of sucrose ($C_{12}{H}_{22}{O}_{11}$)

Q. The mass of 100 molecules of sucrose
$C_{12}{H}_{22}{O}_{11}$ is g.

Q. 2 g mixture of glucose and sucrose is dissolved in 1 litre water at 298 K to develop an osmotic pressure of 0.207 atm. Calculate percentage composition of glucose and sucrose by mole as well as by mass.

Q.

STATEMENT-1 : Sucrose on hydrolysis gives glucose and fructose.
STATEMENT-2 : The formula of sucrose is $C_{12}{H}_{22}{O}_{11}$.

Q. How many atoms are contained in one mole of sucrose $\left(C_{12}{H}_{22}{O}_{11}\right)$?
