How Do You Calculate Molal Volume from Molar Volume and Molecular Weight?

[physstudent1]

The exact question I have to answer isn't about Molar and Molal volume but I need molal volume to plug into the equation for diffusivity coefficients. I have the molar volume of vitamin E 603cm^3/mol and its MW 430.7 and I need to find its molal volume cm^3/(g*mol) but I'm getting pretty confused can anyone help

Molarity (in units of mol/L, molar, or M) or molar concentration denotes the number of moles of a given substance per liter of solution. (Wiki)

Molality (mol/kg, molal, or m) denotes the number of moles of solute per kilogram of solvent (not solution). (Wiki)

What are the details of the problem?
