1. Concentrated sulfuric acid is 18M. What volume of water would be needed to dilute 25mL of concentrated H2SO4 solution to 3M?
a. 25mL
b. 50mL
c. 75mL
d. 125mL
e. 150mL
The answer is 125 which I understand now with the explanation they provided (The M1V1=M2V2), but I just learned about Normality vs Molarity...apparently not well though Why don't we multiply the molarities by 2 and use Normality for the equation N1V1= N2V2 since H2SO4 has 2 Hs? When exactly do we use normality then if it's not used in this case? Thank you in advance!
