Chemistry: How many moles of Ag+ are in 7.2 g of AgCl

[From: ] [author: ] [Date: 11-11-27] [Hit: ]

2g of AgCl into moles using the molar mass (143.32g).7.2/143.32 = ~0.Then you use ratio of 1 mole of Ag : 1 mole of AgCl and get approximately 0.......

How many moles of Ag+ are in 7.2 g of AgCl? Answer in units of mole. Can you please show me how to do this? Thank you!

You first need to convert 7.2g of AgCl into moles using the molar mass (143.32g).
7.2/143.32 = ~0.05 moles of AgCl

Then you use ratio of 1 mole of Ag : 1 mole of AgCl and get approximately 0.05 moles of Ag.

Molar weight of AgCl: 108 + 35.5 = 143.5g
Mole of Ag+ = mole of AgCl: 7.2/ 143.5 = .05 mol
