molar mass of "C_2H_6O" is 46
moles of ethanol in 4.6 g = "4.6\/46=0.1 moles"
as one molecule contains 9 atoms then similarly 1 mole of ethanol will contain 9 moles of atoms and similarly 0.1 moles of ethanol will contain 0.9 moles of atoms
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
