Homework Help: Chemistry

Posted by Denise on Monday, June 25, 2012 at 10:20pm.

We did a lab to find the atomic mass of Magnesium. We used an eudiometer and HCL and a mg ribbon.

Explain in terms of moles, limiting reactants and experimental feasibility, why we use concentrated HCl (12M) instead of 1M or 6M??


Would the calculated atomic mass be higher, lower, or the same as the expected value if you ignored the vapor pressure of water?
