Calculate the original concentration of a solution

 

 

Calculate the original concentration of a solution if 29 mL of the original solution was diluted to 360 mL to make a 4.75×10^(-2) M solution. Submit your answer to 3 significant figures.

 

 

 

M1V1 = M2V2

( 참고 https://ywpop.tistory.com/2859 )

 

 

 

M1 = M2V2 / V1

= (4.75×10^(-2)) (360) / (29)

= 0.589655 M

= 0.590 M

 

 

 

답: 0.590 M
