18.7 g of aluminum and 226 g of chlorine gas react until all of
the aluminum metal has been converted to AlCl3. The balanced
equation for the reaction is the following. 2 Al(s) + 3 Cl2(g) → 2
AlCl3(s) What is the quantity of chlorine gas left, in grams, after
the reaction has occurred, assuming that the reaction goes to
completion? (The formula mass of aluminum metal, Al, is 26.98
g/mol, and the formula mass of chlorine gas, Cl2, is...
