Question

.The mass of 3.01 x 1022 molecules of NH3 is​

Answer 1

Answer:

Mass = 8.5 g. Hence, the Mass of the Ammonia is 8.5 g.

Answer 2

Hi there! Hope it helps :)

Answer:

0.85 g

Explanation:

Moles of Ammonia=  No. of molecules/ Avagadro's number

Moles of Ammonia= 3.01 ×  $10^{22}$/ 6.02 ×  $10^{23\\}$

Moles of Ammonia= 0.05

1 mole ammonia weighs 17g.

Therefore, 0.05 mole has mass -

=0.05 x 17 = 0.85 g

Mass= 0.85 g
