You have a typo or something.
o.752 g per mol of H2 gas
Makes no sense to me.
A mol of H2 is 2 grams because H has atomic mass of 1
If you want a mol of H2
You need 2/3 of a mol of Al
A mol of Al has mass of 27 grams
so
2/3 of 27 = 18 grams of Al
Remember, I do not know what your question is.
What volume of Al metal have density 2.70 g/cm3 is required to produce o.752 g per mol of H2 gas by following reaction
2Al +6HCL ----- AlCl3+3H2
