`2.82` g of glucose is dissolved in 30 g of water. Calculate the mole fraction of glucose and water.

Text Solution

Verified by Experts

Mass of glucose `= 2. 82 g`
No. of moles of glucose `= (2. 82)/( 180) = (30)/(18) = 1. 67`
` x _(H _(2)O)= (1. 67)/( 1. 67 + 0.016) = (1. 67)/( 1. 686) =0.99`
`therefore x _(H _(2)O) + x _("glucose") =1`
` 0.99 + x _("glucose")=1`
`x _("glucose")=1-0.99 =0.01`
