3 What volume of 50 M H2SO4 should be diluted to 100 mL to p

3. What volume of 5.0 M H2SO4 should be diluted to 100 mL to prepare a 0.25 M H2SO4 M solution?

Solution

Use C1V1= C2V2

C1= initial concentration

V1= volume of initial concentration solution to be used

C2= final concentration needed

V2= final volume .

5.0* x= 0.25*100

X= 5 ml

so you take 5 ml of the 5 molar solution and dilute it to 100 ml
