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.

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.

i had this on my unit activity, i can you if you are a plato student. are you a plato student?
