The Molarity is equal to the number of moles divided by the liters.

M=mol/L

M=0.120 mol/5.0 L

M=0.024

so the molarity is 0.024 M

### How do you find the concentration of 3.50g of potassium chromate in 100 ml water?

K2CrO4
Molarity (concentration) = moles of solute/Liters of solution
(100 ml = 0.100 Liters )
Find moles K2CrO4 first.
3.50 grams = (1 mole K2CrO4/194.2 grams)
= 0.01802 moles K2CrO4
----------------------------------------------next
Molarity = 0.01802 moles K2CrO4/0.100 Liters
= 0.180 M K2CrO4
