Molecular weight of oxygen is 32.
Thus the number of moles present in 16 g of OO2 will be 0.5
Number of molecules present will be 0.5NA
Number of gram atoms will be 0.5×2NA=NA
( Since one molecule of oxygen contains 2 atoms of oxygen)
1 mol of a gas occupies 22.4l at STP, thus given sample will occupy 11.2l at STP.
No. of protons=No.of gram atoms×8=8NA
(Since one oxygen atom contains 8 protons)
