Question

What is the concentration of HNO₃ if 0.344 mol are present in 815 mL of the solution?

Express your answer with the appropriate units.

Answer 1

The concentration of HNO₃ in the solution is approximately 0.4221 Molar (M).

This means that every 1 liter of the solution contains 0.4221 moles of HNO₃.

To calculate the concentration of HNO₃ in the solution, we can follow these steps:

Convert the volume from mL to L:

815 mL = 0.815 L

Use the formula for concentration:

Concentration = moles of solute / volume of solution

Plug in the values:

Concentration = 0.344 mol / 0.815 L

Calculate the concentration:

Concentration ≈ 0.4221 M

Therefore, the concentration of HNO₃ in the solution is approximately 0.4221 Molar (M).

This means that every 1 liter of the solution contains 0.4221 moles of HNO₃.
