Answer:
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.
