Question

60g of urea dissolved in 180g of h2o .find mole fraction of solvent​

Answer 1

Answer:

10/11 is the mole fraction of solvent

Explanation:

Mole weight of urea = 60 g

Mole weight of water = 18

no . of moles urea = 60/60 =1

no of moles water = 180/18 = 10

moles fraction of urea = (moles of urea) ÷ (total moles)

=> 1/(10+1)

=>1/11

mole fraction of the solvent = (moles of solvent) ÷ (total moles)

=> 10/11

Answer 2

Answer:

0.99

Explanation:

formula: x A =na/na+nb. xh2o =nh2o/nh2o +nurea ... nurea =60/60=1 nh2o =180/18 =10 =10 /11 =0.99.....hope its help u...❤TC mark as brain list....
