Question

If 18g of glucose is dissolved in 90g of water . Calculate the mole fraction of both components.​

Answer 1

Answer:

Explanation:

Molecular mass of water= 2×1+1×16=18g

=2×1+1×16=18g

For 90g178.2g water n  

A  =5

Molecular mass of glucose  6×12+12×1+6×16=180g

For 18g glucose n  

B =0.1

Now,  X  

B =  0.1+5 0.1  =0.0196 ~0.02
