Question

8gm O2 has the same number molecules as in

Answer 1

Answer:

0.25 mole of any substance

Explanation:

molecular mass of O2 is 32gm

given mass = 8gm

therefore no. of moles =0.25 nos.

Answer 2

molecular mass of O2 = 32g=1mole

moles in o2= 8/32=1/4 moles

molecules in 1/4 moles =6.022*10^23/4

=1.5055*10^23 molecules in8g of O2
