Question

What is the molarity of a solution of 1/2 mol of cu(no3)2 in 1/2 L water

Answer 1

molarity is mole divided by volume in litres.
0.5mol divide by 0.5L = 1M

Answer 2

Answer : The molarity of solution is, 1 mole/L

Explanation : Given,

Moles of
`Cu(NO_3)_2` =
`(1)/(2)mole`

Volume of water =
`(1)/(2)L`

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

Formula used :

`Molarity=\frac{\text{Moles of }Cu(NO_3)_2}{\text{Volume of solution}}`

Now put all the given values in the above formula, we get the molarity of the solution.

`Molarity=((1)/(2)mole)/((1)/(2)L)=1mole/L`

Therefore, the molarity of solution is, 1 mole/L
