Answer 2

Answer:

explanation

Explanation:

molarity=moles/ volume===>moles=molarity*volume=2*1.5=3

trick to find limiting reagent=moles/ stoichiometric coefficient

BALANCED equation

3CuSo4+2Al---> al2(so4)3+3Cu

moles of aluminium/ stoichiometric coefficient=(40/27)/2=0.7

Moles of cuso4/stoichiometric coefficient=3/3=1

..Aluminium is a limiting reagent.

moles of cu/stoichiometric coefficient=moles of aluminium/s.c

===>w/63.5*3=1.4/2
