This chemical formula doesn't exist.Ag2SO4 and Ag2S are solids.
To find out how much silver can be produced from 125g of Ag2S, you need to consider the molar mass of Ag2S, which is 247.8 g/mol. This means that 1 mole of Ag2S produces 2 moles of silver (Ag). Therefore, you can calculate the amount of silver produced from 125g of Ag2S using stoichiometry.
The moles of silver(at wt = 107.86) in the sample is 21.6/107.86= 0.2 The moles of sulfur (at. wt. = 32.06) in the sample is (24.8- 21.6)/32.06 = 0.1 The molar ratio is 2:1 so the formula of the mineral is Ag2S The equation is Ag2S + O2 -> 2Ag + SO2
Argentite is a mineral composed of silver sulfide (Ag2S). It does not contain a metal in the conventional sense, but rather it is a silver compound mixed with sulfur.
The chemical reaction is:2 AgNO3 + Na2S = 2 NaNO3 + Ag2S(s)
