molarity help
« on: February 04, 2009, 02:44:30 PM »
Commercially available concentrated sulfuric acid is 18.0 M H2SO4. Calculate the volume of concentrated sulfuric acid required to prepare 2.10 L of 0.440 M H2SO4 solution.
I dont know exactly what im doing with this but im doing M1V1=M2V2
18V1=2.1x.44
v1=.05
what am i doing wrong?

Perhaps significant figures.
