Explanation:
<u>Answer:</u> The concentration of the diluted solution is 0.4788M
<u>Explanation:</u>
To calculate the concentration of the diluted solution, we use the following equation:

where,
are the molarity and volume of HCl solution
are the molarity and volume of the diluted HCl solution.
We are given:

Putting values in above equation, we get:

Hence, the concentration of the diluted solution is 0.4788M
95.611 g/mol that's the answers
