Question

How many grams of aluminum (Al) would react completely with 1350 grams of copper (II) chloride (CuCl2) according to the following equation?
2Al + 3CuCl2 ---> 2AlCl3 + 3Cu

Answer 1

180.7 grams

Tell me if I'm wrong :)

Answer 2

lol instead of blurting out an answer you could help OP understand how to solve the question.

--------

First you need to convert the mass given to moles.

then relate the moles of copper(II) chloride to the moles of Al, using the stoichiometric coefficients.

\(\sf \dfrac{moles~of~CuCl_2}{CuCl_2's~coefficient}=\dfrac{moles~of Al}{Al's ~coefficient}\)

plug in your values, and solve.

Convert moles to mass.
