Question

To what volume should 5.06 mL of an 7.83 M sulfuric acid solution be diluted in order to obtain a final solution that is 2.36 M?

Answer 1

the answer is 16.8 mL H2SO4 (aq).

the formula for dilation is M1*V1=M2*V2, where M is the molarity and V is the volume.

so plugging in...

1. (7.83)(5.06)=2.36*V2

2. multiply 7.83 and 5.06 then divide that by 2.36

3. V2= 16.788050...

4. to three sigfigs (because the problem has a minimum of 3) is 16.8 mL H2SO4 (aq).

i hope this is correct! i did it without pencil and paper and i’m currently learning this too! if it’s wrong i’m so truly sorry :(
