Question

6. Calculate the molarity of a 3.5 L that contains 2.8 mol of HNO3.

Answer 1

The molarity of HNO3 is 0.8 M

Step-by-step explanation

Given that

The volume of HNO3 is 3.5L

The number of moles of HNO3 is 2.8

To find the molarity of HNO3, follow the steps below

Molarity is defined as the mole of solute per unit volume of the solution.

`\begin{gathered} \text{ Molarity }=\text{ }(mol)/(Volume) \\ \\ \text{ Molarity }=\text{ }(2.8)/(3.5) \\ Molarity\text{ }=0.8M \end{gathered}`

Hence, the molarity of HNO3 is 0.8 M
