formula of glucose - c6H12O6
so molecular mass of glucose - 6x12 +12x1+6x16= 72+12+96=180g
means one mole of glucose molecular mass 180 g
also ,in one mole of glucose there is 6.022 x10 ^23 electrons
so in 180 g of glucose contains 6.022x10^23 electrons
then 3g of glucose contains 6.022x10^23/180 x 3 = 10^22 electrons (approximately)
