Answer:
0.231 mol HCl
Explanation:
What we know:
- Volume of HCl solution = 0.70 L
- Strength of HCl solution = 0.33 M
Here M stands for molarity. Molarity is the number of moles of the substance present per Litre of solution. So in place of M we can write moles / L
Number of moles of HCl solution = Volume of HCl solution x Strength of HCl solution
= 0.70 L x 0.33 moles / L
= 0.231 mol HCl
0.231 moles of HCl are present in 0.70 L of a 0.33 M HCl solution
