Homework Help: chemistry

Posted by Leny on Thursday, November 25, 2010 at 4:18am.

I did an experiment with a sand sample which contains fine metallic aluminium and I wanted to measure how much of this metallic aluminium is in the sample. I used the NaOH solution in order to let react the aluminium and collect the H2. From the H2 amount I thought I could calculate the amount of aluminium in the sample. However now I do not know how to calculate it, I probably should first calculate the MH2 (mol), then MAl (mol) and from this I could go to Mal (g). Could you help with the equations?
