In a), where did the 135 come from?
In b), where did the 42 come from?
See my answer to your previous post of the same question.
Determine the percentage composition of each of the following compounds
a) NaCl
b) AgNO3
c) Mg(OH)2
for NaCl i got na=23/135=0.17 x 100= 17% Cl=35/135=0.26 x 100=26%
for AgNO3 i got 108/42 which im sure was wrong and i didn't get how to complete the problem..
for Mg(OH)2 i didn't have a clue
