Answer:
No. of moles =1.875
No. of molecules of O2 = 11.3 ×10²³
No. of protons =30
Explanation:
No. of mole = Given mass/molecular mass
No. of moles of O2= 60/32
=1.875
No. of molecules in 1 moles of O2= 6.022×10²³
So,
no of molecules in 1.875 moles =
6.022×10²³×1.875 = 11.3×10²³
No. of protons in 1 mole of O2= 16
No. of protons in 1.875 moles =
16×1.875 = 30
