Question

Rucs
10g. Sucrose is disolved in 100g. find wt by wt%​

Answer 1

Answer:

34.3mmHg

Explanation:

Mass of glucose = 10 g

No. of moles of glucose = 0.0556

Mass of sucrose = 20 g

No. of moles of sucrose = 0.0585

Mass of water = 100 g

No. of moles of water = 5.556

Total number of moles = 5.556+0.0585+0.0556

=5.67

Mole fraction of water =

5.67

5.556

Vapour pressure of solution = Mole fraction of water ×P

0

=

5.67

5.556

×35=34.3mmHg
