Question

What is the mole fraction of solute in aqueous solution
of 20% NaOH?​

Answer 1

Answer:

Assuming 20% by mass, 6.25 M

for 100g of solution, we have 20g NaOH and 80g water. So, we have 0.5 moles of NaOH and 80 mL of water, i.e. 0.080 L of water.

So, the molarity is Moles of NaOH/litres of water=0.5/0.08=6.25 M
