Question

What is the molarity of a solution that contains 0.500 mole of kno3 dissolved in 0.500-liter of solution?

Answer 1

Answer : The molarity of solution is, 1.00 M

Explanation : Given,

Moles of
`KNO_3` = 0.500 mol

Volume of solution = 0.500 L

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

`\text{Molarity}=\frac{\text{Moles of }KNO_3}{\text{Volume of solution (in L)}}`

Now put all the given values in this formula, we get:

`\text{Molarity}=(0.500mol)/(0.500L)=1.00mole/L=1.00M`

Therefore, the molarity of solution is, 1.00 M
