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 :(
