Question #0a95e Chemistry Stoichiometry Stoichiometry 1 Answer MeneerNask Jul 1, 2015 The answer is B Explanation: Relative atomic mass of #Al=27# and #Cl=35.5# To form #AlCl_3# you need these in the ratio: #(m(Cl))/(m(Al))= (3*35.5)/(1*27)=106.5/27-># #m(Cl)=106.5/27*m(Al)=106.5/27*13.5=53.2g# The mass of the #AlCl_3# #m(AlCl_3)=13.5+53.2=66.7g# Answer link Related questions How do you solve a stoichiometry problem?
