moles SO2 = 3.2 g/64 g/mol= 0.05
molecules SO2 = 0.05 x Avogadro's number = 0.05 x 6.02 x 10^23=3.01 x 10^22
atoms = 3 x 3.01 x 10^22 =9.03 x 10^22
molecules SO2 = 0.05 x Avogadro's number = 0.05 x 6.02 x 10^23=3.01 x 10^22
atoms = 3 x 3.01 x 10^22 =9.03 x 10^22
i know get lost
plz mark me as brainliest
so slow u r of no use
why

molar mass SO2 = 64 g/mol
moles SO2 = 3.2 g/64 g/mol= 0.05
molecules SO2 = 0.05 x Avogadro's number = 0.05 x 6.02 x 10^23=3.01 x 10^22
atoms = 3 x 3.01 x 10^22 =9.03 x 10^22.
no. of molecules = no. of moles × avagadros no.
no. of molecules = 3.2/64 × 6×10^23 = 3×10^22
