6.0 M HNO3 0.500 M HNO3 110 mL

6.0 M HNO3 0.500 M HNO3 110 mL

 

 

a) How many milliliters of a stock solution of 6.0 M of HNO3

would you have to use to prepare 110 mL of 0.500 M HNO3?

 

b) If you dilute 10.0 mL of the stock solution to a final volume of 0.250 L,

what will be the concentration of the diluted solution?

a)

MV = M’V’

( 참고 https://ywpop.tistory.com/2859 )

 

(6.0 M) (? mL) = (0.500 M) (110 mL)

 

? = (0.500) (110) / (6.0) = 9.17 mL

 

 

 

 

b)

MV = M’V’

(6.0 M) (10.0 mL) = (? M) (250. mL)

 

? = (6.0) (10.0) / (250.) = 0.24 M
