18 g of glucose `(C_6H_(12)O_(6))` is added to 178.2g of water. The vapour pressure of water for this aqueous solution at `100^@C` is

7.60Torr

76.00Torr

752.40Torr

759.00Torr

Text Solution

Verified by Experts

The correct Answer is:

`(P^(@)- P_(S))/(P_(S)) = X_("solute") = (n)/(N), (760-P_(S))/(P_(S)) = ((18//180))/((178..2//18))=(0.1)/(9.9)`
`760-99- P_(S) xx 99 = P_(S), P_(S)= 752.4`
