Answer:
Step-by-step explanation:
To determine the volume of the 0.30 M HNO3 solution needed to supply 2.0 mol of HNO3, we can use the equation:
Molarity (M) = moles of solute / volume of solution (in liters)
Given that the molarity (M) of the HNO3 solution is 0.30 M and the number of moles of HNO3 needed is 2.0 mol, we can rearrange the equation to solve for the volume of the solution.
Volume of solution = moles of solute / Molarity
Volume of solution = 2.0 mol / 0.30 M
Volume of solution ≈ 6.67 liters
Therefore, approximately 6.67 liters of the 0.30 M HNO3 solution is needed to supply 2.0 mol of HNO3.
