How many grams of Al2(SO4)3 are needed to make
87.5 g of 0.3 m Al2(SO4)3 solution? (Atomic weights of
Al = 27, S = 32, O = 16)
A. 102.6/(87.5 x 1000)
B. (87.5 x 102.6)/1000
C. 87.5/1102.6
D. 102.6/(87.5 x 1102.6)
E. (87.5 x 102.6)/1102.6
Kaplan has its own solution, and I am wondering is there any other way to approach this question. If you know how to do this Q, plz explain. Thanks!
