Question

There are two containers: one container with a 0.15 molar solution of compound A and another with 0.20 molar solution of compound B. What is true about these two containers? O Container A has more moles than B. Container B has more moles than A. They contain an equal number of moles. Not enough information is given.

Answer 1

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

Step-by-step 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.
