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

A

76.00 torr

B

752.40 torr

C

759. 00 torr

D

7.60 torr

Text Solution

Verified by Experts

The correct Answer is:
B
Moles of gglucose `=18/180 = 0.1`
Moles of water `= (178.2)/18 = 9.9`
Total moles `= 0.1 + 9.9 = 10`
`p_(H_2O) =` Mole fraction `xx` Total pressure `=9.9/10 xx760`
`=752. 4` Torr
