Answer: 4.8 mL of 1.043 M acetic acid that is needed to prepare 50.0 mL of 0.10 M acetic acid

Explanation:

According to the dilution law,

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1[/tex] = molarity of stock [tex]CH_3COOH[/tex] solution = 1.043 M

[tex]V_1[/tex] = volume of  stock [tex]CH_3COOH[/tex] solution = ?

[tex]M_1[/tex] = molarity of diluted [tex]CH_3COOH[/tex] solution = 0.10 M

[tex]V_1[/tex] = volume of diluted [tex]CH_3COOH[/tex]solution = 50.0 ml

Putting in the values we get:

[tex]1.043\times V_1=0.10\times 50.0[/tex]

[tex]V_1=4.8ml[/tex]

Therefore, volume  in mL of 1.043 M acetic acid (CH3COOH) that is needed to prepare 50.0 mL of 0.10 M acetic acid is 4.8
