Answer : The mass of hydrochloric acid (in grams) needed for the solution is, 25.5 grams.
Explanation : Given,
Molarity of [tex]HCl[/tex] = 2.00 M
Volume of solution = 0.350 L
Molar mass of [tex]HCl[/tex] = 36.468 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
[tex]\text{Molarity}=\frac{\text{Mass of }HCl}{\text{Molar mass of }HCl\times \text{Volume of solution (in L)}}[/tex]
Now put all the given values in this formula, we get:
[tex]2.00M=\frac{\text{Mass of }HCl}{36.468g/mole\times 0.350L}[/tex]
[tex]\text{Mass of }HCl=25.5g[/tex]
Therefore, the mass of hydrochloric acid (in grams) needed for the solution is, 25.5 grams.
