Question

34.2 gm of sucrose(C12H22011)are dissolved in 180gm of water. Calculate the number of
oxygen atoms in the solution.
kindly help me please​

Answer 1

Explanation:

Molar masses of cane sugar and water are 342 g/mol and 18 g/mol respectively.

Number of moles of can sugar =

342g/mol

34.2g

=0.1mol

Number of moles of water =

18g/mol

180g

=10mol

Mole fraction of cane sugar =

0.1+10

0.1

=0.0099

The relative lowering of vapour of pressure of solution is equal to the mole fraction of cane sugar.

The relative lowering of vapour of pressure will be 0.0099.
