Question

Calculate the mass of Ammonia present in 1.5 x 10^ 23 molecules

Answer 1

Mass of 1 mole of NH3 molecule = 17 g.

So 6.023 x 1023 molecules = 17g

∴1.5 x 1023 molecules = 17/ 6.023 x 1023 * 1.5 x 1023 molecules = 4.23 g

Answer 2

Answer:

Hey mate,

Your answer is as follows:

Mass of 1 mole of NH3 molecule = 17 g.

So 6.023 x 1023 molecules = 17g

∴1.5 x 1023 molecules = 17/ 6.023 x 1023 * 1.5 x 1023 molecules = 4.23 g
