Question

What is the molarity of 15 moles of a 5 L solution?

Answer 1

3m

Step-by-step explanation:

Molarity equation = Moles of solute/liters of solution

Plug values in and get 3 :)

I am not sure the units are correct so check those but that should be the answer

Answer 2

The molarity of the solution is

5.1 mol/L

.

The solution is said to be

5.1 molar

.

The shorthand way to indicate molarity is

5.1 M

, which is pronounced

5.1 molar

, and is how it is written on the label of its container.

Step-by-step explanation:

Molarity (M)

=

moles of solute

liters of solution

The volume of the solution is given in mL. The volume is required to be in liters, so

975 mL

must be converted to liters.

1 L=1000 mL

975

mL

1000

mL

=

0.975 L

Molarity (M)

=

0.975

L

=

5.1 mol/L

rounded to two significant figures
