Normality to Grams Chemisty Problem
« on: July 24, 2005, 11:40:31 PM »
I am in a basic chemistry course in college.  Can someone please verify that I have done this problem correctly.

Here is the problem:

How many grams of H2SO4  are needed to prepare 500 mL of a .25 N solution?

Here is my attempt to solve:

First, I found the formula weight of the H2SO4.  Then I decided to find the M value from the Normality value.   I took the .25 Normality number and divided it by 2 (the number of equivalents) which gave me an answer of .125 M.  From there I multiplied .125 M by .5 L and got an answer of .0625 moles H2SO4.  I converted moles to grams and came up with the answer of 6.125 grams H2SO4 .   I have a big test in the morning and would like to know that I was able to solve this correctly in case my professor puts a similar problem on the test.  Your input would be appreciated.
