Question

(1.) If at 100.0 mL solution contains 0.850 moles of a solute, what is the molarity ?
(2.) If the molarity of a solution is 12 M and the volume of the solution is 1.0 L, how many moles of solute does the solution contain ?

Answer 1

Answer:

See below

Explanation:

1)  Moles / volume

  .85 mole / .1 liter = 8.5 M

2)   12 moles are contained in one liter

Answer 2

Answer is 1 Moles volume
.85 mole / .1 liter = 8.5 M
2) 12 moles are contained in one liter
