Question

How many milliliters of 0.1 M KNO3 solution would contain 0.02 moles of the solute?

Answer 1

Answer:

200mL

Explanation:

0.1 M of solution means 0.1 mol/L of solute.

That means 0.1 mol of solute is in 1L solution.

So 1mol solute will be in 10L solution.

So 0.02 mol solute will be in 10×0.02 L solution.

= 0.2 L solution

0.2 L = 200mL solution.

So 200mL of 0.1M KNO3 solution will have 0.02 moles of KNO3.
