E. 15 (7th Edition)

Postby Austin Clack » Thu Oct 04, 2018 7:06 pm

Problem E.15 in the 7th edition textbook of a metal hydroxide without specifying what the metal is. I was able to deduce that the metal is calcium, however, the question refers to the "mass of the sulfide of this metal'. How is sulfide involved in this problem?

It just arbitrarily asks, find what the mass of the metal sulfide would be, its not related to the previous measurements, but you should be able to find it if you know the mass of sulfide.

First figure out what the metal is based on its molar mass and then find the molar mass of the metal sulfide.
