Question

Calculate no. Of atoms present in 0.4 mole molecules of nitrogen

Answer 1

Answer:

Explanation:

0.5 moles of nitrogen molecules = 6.022 ×10^23 × 0.5 = 3.011×10^23 molecules As 1 molecule of nitrogen contains 2 atoms of nitrogen, So, 3.011×10^23 molecules of nitrogen will contain 3.011×10^23× 2 atoms

Answer 2

Answer:

4.8176 × 10²³ atoms of nitrogen

Explanation:

0.4 mole molecules of nitrogen

= 0.4 × 6.022 × 10²³ molecules of nitrogen

= 2 × 0.4 × 6.022 × 10²³ atoms of nitrogen (1 molecule of nitrogen has two nitrogen atoms{N₂} )

= 4.8146 × 10²³ atoms of nitrogen
