How many grams of silver sulphide are formed when 1.90 g of silver reacts with 0.280 g

Question

of hydrogen sulphide and 0.160 g of oxygen?

Answer 1

first step: write the reaction equation: 4Ag + O2 + 2H2S = 2Ag2S + 2H2O
next, express each amount in moles
You can see that you will need 4 moles of Ag and 2 moles of H2S for each mole of O2
So check your amounts to see which will run out first. Then you can see how many moles of Ag2S will be formed, and express that in grams.
