What is the percentage composition of nitrogen in silver nitrate?

Answer 1

You need to know the formula for silver nitrate which is AgNO3

Then you work out the MR of silver nitrate = 108+14+(16x3) = 170

Then you work out the MR of the nitrogen contained in silver nitrate. There is just one nitrogen atom so it would be 14.

Then you need to work out the percentage nitrogen in silver nitrate like you would doing any percentage.

(MR nitrogen/MR silver nitrate) x 100%
(14/170)x100 = 8.2%

Hope this helps
