Chemistry Question..

[From: ] [author: ] [Date: 11-05-07] [Hit: ]
which means the final solution is 10 times less concentrated, so you will need a tenth part of you final solution volume (1L) to make a 1/10 dilution,......
1) What volume of a 10 mol/L H2SO4 solution is needed to make 1 L of 1.0 mol/L solution of H2SO4?

Thanks :P

Your final solution contains n(H2SO4) =1.0 mol/L * 1 L = 1.0 mol of sulfuric acid which is exsactly the amount of acid that was taken from your stock solution (10 mol/L).
V(H2SO4) = 1.0 mol/ 10 mol/L = 0.1 L or 100 ml

To make it even simpler: it's a 1 to 10 dilution, which means the final solution is 10 times less concentrated, so you will need a tenth part of you final solution volume (1L) to make a 1/10 dilution, and 1/10 of 1 L is 100ml :)

you're welcome :)
