What is the molarity of a 0.30-liter solution containing 0.50 moles of H2SO4?
A 1.7M
B 0.6M
C 0.8M
D 0.15M

Answer 1

1.7M

Step-by-step explanation:

Given parameters:

Volume of solution = 0.3L

Number of moles = 0.5moles

Unknown:

Molarity = ?

Solution:

The molarity of a substance is the number of moles of solute that can be found in the volume of a solution.

Molarity =
`(number of moles )/(volume)`

Insert the parameters and solve;

Molarity =
`(0.5)/(0.3)` = 1.7M
