<u>Answer:</u> The volume of HCl needed is 0.250 L
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
<u>For sodium carbonate:</u>
Molarity of sodium carbonate solution = 0.500 M
Volume of solution = 0.750 L
Putting values in above equation, we get:
The chemical equation for the reaction of sodium carbonate and HCl follows:
By Stoichiometry of the reaction:
1 mole of sodium carbonate reacts with 2 moles of HCl
So, 0.375 moles of sodium carbonate will react with = of HCl
Now, calculating the volume of HCl by using equation 1:
Moles of HCl = 0.750 moles
Molarity of HCl = 3.00 M
Putting values in equation 1, we get:
Hence, the volume of HCl needed is 0.250 L
