Ronnie Palmer · Answer 1

Container having 0.20 moles of compound has more moles than the container with 0.15 moles of compound A.

Explanation:

Molarity is defined as ratio of moles of compound to the volume of solution in liters.

Molarity of compound A solution = 0.15 molar = 0.15 mol/L

This means that 0.15 moles of compound A are present in 1 L of solution.

Molarity of compound B solution = 0.20 molar = 0.20 mol/L

This means that 0.20 moles of compound B are present in 1 L of solution.

As we can see that, 0.15 mol < 0.20 mol which indicates that container with compound B has more mole the the container with compound A moles.
