#"The molar mass of acetic acid is "60.05*g*mol^-1#

Explanation:

And how did we get this quantity? All I did was take the molar mass of each element in the formula of acetic acid, weighted according to its frequency, i.e.

#"Molar mass"# #=#

#{2xx12.011(C)+ 4xx1.00794(H)+2xx15.999(O)}*g*mol^-1#

#=# #60.05*g*mol^-1#.

And can you tell me how many acetic acid molecules there are in such a mass?
