Question

4.6g of ethanol (C2 H6 O) is found in a bottle of alcohol. calculate the number of mole of atoms in the bottle.

Answer 1

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
