No of molecules = weight given ÷ molecular number × avargardo number = 8÷16×6.022×10^23=3.011×10^23 molecules molecular weight oxygen is 16 g.
or something else
no of moles
it will take some time
ok
I promise to give you the answer soon
plz wait for a while
number of moles of atoms = mass of elements / molar mass of elements
8g of oxygen = 1 mole of oxygen
soory above one is mistaken
3.011×10^23 i can not understand the weight of (O) is 16g
