ANSWER Molecular weight of oxygen is 32.
ANSWER Molecular weight of oxygen is 32.Thus the number of moles present in 16 g of O2 will be 0.5
ANSWER Molecular weight of oxygen is 32.Thus the number of moles present in 16 g of O2 will be 0.5Number of molecules present will be 0.5NA
ANSWER Molecular weight of oxygen is 32.Thus the number of moles present in 16 g of O2 will be 0.5Number of molecules present will be 0.5NANumber of gram atoms will be 0.5×2NA=NA( Since one molecule of oxygen contains 2 atoms of oxygen)
ANSWER Molecular weight of oxygen is 32.Thus the number of moles present in 16 g of O2 will be 0.5Number of molecules present will be 0.5NANumber 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.
