(real number)
The molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
M1V1 = M2V2
Where;
- M1 = molarity of a base
- M2 = molarity of acid
- V1 = volume of base
- V2 = volume of acid
M1 × 200 = 50 × 5
200M1 = 250
M1 = 250/200
M1 = 1.25M
Therefore, the molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.
