Chromium metal can be produced from the high temperature

Chromium metal can be produced from the high temperature reaction of Cr2O3(chromium(III) oxide) with silicon or aluminum by each of the following reactions:

Cr2O3+2Al-->2Cr+Al2O3

2Cr2O3+3Si-->4Cr+3SiO2

1) Calculate the number of grams of aluminum required to prepare 87 g of chromium metal by the first reaction.

2) Calculate the number of grams of silicon required to prepare 87 g of chromium metal by the second reaction.
