Answer:
Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.
Explanation:
Molarity of HCl Joan has access to = [tex]M_1=2.12 M[/tex]
Volume of 2.12 M of HCl Joan use = [tex]V_1=?[/tex]
Molarity of HCl Joan desired = [tex]M_2=0.053 M[/tex]
Volume of 0.053 M of HCl Joan can prepare = [tex]V_2=25 mL[/tex]
[tex]M_1V_1=M_2V_2[/tex]
[tex]V_1=\frac{M_2V_2}{M_1}[/tex]
[tex]=\frac{0.053 M\times 25 mL}{2.12 M}=0.625 mL[/tex]
Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.
