how many grams of AlCl3 is produced if 15.5 grams of Al are reacted with excess Cl2 gas? 2Al + 3Cl2 > 2AlCl3

1 answer

mols Al = grams/atomic mass Al
Using the coefficients in the balanced equation, convert mols Al to mols AlCl3.
Now convert mols AlCl3 to grams. g AlCl3 = mols AlCl3 x molar mass AlCl3.
