Answer 2

Answer: Mass of Ag is 3g in 3.45g of Ag₂S.

Explanation: The mass of Ag₂S is given which is 3.45g .For taking out the mass of Ag present in Ag₂S, these are the following steps:

$Atomic\ mass\ of\ Ag=107.9u\\Atomic\ mass\ of S=32.9u\\Molecular\ mass\ of\ Ag_{2}S=248.7\\Moles\ of\ Ag_{2}S=3.45/248.7=0.01387214\\Mass\ of\ Ag\ present\ in\ 3.45g\ Ag_{2}S=0.01387214\times107.9\times 2=2.993g=3g$
