i) 6022 atoms of hydrogen
ii) 24088 molecules of hydrogen

(please include explanation, thank you)​

Answer 1

Answer: i) 1 into 10 raised to -20

ii) 4 into 10 raised to -20

Explanation:

Moles = number of atoms/ avogdro number

i) = 6022/6.022× 1023

= 1000× 10-23

= 1×10-20

ii) = 24088/ 6.022 × 1023

= 4000× 10-23

= 4× 10-20
