How do I convert molar volumes with different initial units?

[subopolois]

hello everyone, i have a question involving molar volumes. if i have to find the difference in molar volumes, which have initial units of cm^3 mol^-1. i know i subtract them, but is the question asks for the answer in cm^3, what do i do?

When you are describing "MOLAR VOLUME" the 'per mole' is understood and thus the units are cm^3 (cm^3/mol if you want to be pedantic).

so if i have a molar volume of 2.784 cm^3 mol^-1 its there is nothing that i have to convert?

Yes, you could say 2.784 cm^3 mol^-1 or just 2.784 cm^3 if it was understood that you were describing a molar volume.
