Explanation:

Use the formula

n

=

m

M

where

n

is the amount in moles (

m

o

l

),

m

is the mass in grams (

g

), and

M

is the molar mass in grams per mole (

g

m

o

l

1

).

To find the molar mass of ethanol:

There are 2

C

atoms (molar mass

12.011

g

m

o

l

),

6

H

atoms (molar mass
