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 $Cu(NO_3)_2$ = $\frac{1}{2}mole$

Volume of water = $\frac{1}{2}L$

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.

$Molarity=\frac{\frac{1}{2}mole}{\frac{1}{2}L}=1mole/L$

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