Answer:

If there are 0.35 moles of something, then there is the number #0.35xxN_A# of that something, where #N_A# #=# Avogadro's number.

Explanation:

So, I have 0.35 moles of ethanol:

thus I have #0.35xxN_A# ethanol molecules .

Now #N_A = 6.022xx10^23#. And if I have 1 mole of ethanol I have a mass of 46.07 g. What is the mass of 0.35 moles of ethanol?
