Question

A solution of glucose in water is labelled by10% by mass. what is the morality and molality of the solution

Answer 1

Answer:

Explanation:

Molarity=No of moles/Volume of solution in litre

10% means 10g in 100g solution

So,mass of solvent=100-10=90g

No of moles=10/180=1/18

Molality=(1/18)/(90/1000)

Molarity=(1/18)/1=1/18

Hope you understood.
