Question

1:)A samle of improve of Ag 1.5gm is heated with Ag to from Ag2S the mass Ag2S form devoice 0.124gm what is prestage yeild of Ag2S​

Answer 1

Answer:

7.20%

Explanation:

a desired balance chemical equation is

2ag+s=ag2s

2 mol =1 mol

2multiply108=216=248g

amount of ag2 s that can be formed from 1.5g of silver

248/216 multiply=1.5=1.722/g

yield of ag2s=0.124/1.772 multiply100=7.20%
