Question

How many numbers of molecules are present In 3 mol of NH, gas?
A) 1.8066 X 1024
B) 1.8066 X 1023
C) 1.8066 X 1022
D) 1.8066 X 1021​

Answer 1

ANSWER :-

Option A

EXPLANATION :-

As we know , NH = nitrogen × hydrogen

1 mole of NH = 14+1 = 15g

1mole or 15g of NH = 6.022 × 10²³ molecules

3 mole or 45g of NH = 3 × 6.022×10²³

= 18.066 × 10²³

= 1.8066 × 10²⁴ molecules of NH
