mass of a molecule and mass of a mole - units?

question states The chemical formula for ethanol is CH3CH2OH. What is the mass for one molecule of ethanol? What about one mole of ethanol?


I have found the molar mass of ethanol to be 46 when I added all of the atomic masses of each atom. However, I the answer choices are confusing me on the units they use - which unit applies to mass of a molecule and which applies to mass of a mole?


46 amu, 46 g
46 g, 46 amu
46 amu, 2.8 x 1025 g
46 g, 2.8 x 1025 amu
