Question

We wish to dilute some 18.4 m h2so4 solution to make 600 ml of a 0.1 m h2so4 solution. how much of the 18.4 m solution should we start with?

Answer 1

We can use the following formula when making diluted solutions from concentrated solutions
c1v1 = c2v2
where c1 is concentration and v1 is volume of the concentrated solution 
and c2 is concentration and v2 is final volume of diluted solution 
substituting the values in the equation
18.4 M x V = 0.1 M x 600 mL 
V = 3.26 mL
volume of 3.26 mL of 18.4 M sulfuric acid solution should be taken and diluted upto 600 mL
