SUMMARY

The discussion focuses on calculating the molal volume of vitamin E using its known molar volume of 603 cm³/mol and molecular weight (MW) of 430.7 g/mol. To derive the molal volume in cm³/(g*mol), one must understand the distinction between molarity and molality, where molality is defined as moles of solute per kilogram of solvent. The user seeks clarification on how to perform this calculation for application in diffusivity coefficient equations.

PREREQUISITES
  • Understanding of molar volume and its units (cm³/mol)
  • Knowledge of molecular weight and its significance in calculations
  • Familiarity with the concepts of molarity and molality
  • Basic grasp of diffusivity coefficients and their relevance in chemical equations
NEXT STEPS
  • Research the formula for converting molar volume to molal volume
  • Study the relationship between molality and molarity in solution chemistry
  • Learn about the calculation of diffusivity coefficients in chemical processes
  • Explore examples of molal volume calculations for various substances
USEFUL FOR

Chemistry students, researchers in physical chemistry, and professionals working with solution concentrations and diffusivity coefficients will benefit from this discussion.

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)
