I cant seem to figure out the right answer for this problem. Can somone tell me the asnwer so I can see where I am miss calculating? Thanks.

How many molecules of ethanol (C_2H_5OH)(the alcohol in alcoholic beverages) are present in 160mL of ethanol?The density of ethanol is .789 g/cm^3

[0000000]

you know the volume and the density, multiply them and you will get the mass of the alcohol . After that look for the molar mass using the periodic table of the elements and divide the mass with the molar mass, that will give you the quantity and after that use the Avogadro constant. That's all
