# Density/Volume Calculator Tool

## Description

This tool calculates the mass density from the molar volume or vice versa. To calculate the mass density, the chemical formula and molar volume should be provided.

## Using the tool

1. Select Density/Volume Calculator from the Tool menu on the SasView toolbar.

2. Enter the empirical formula of a molecule. For mixtures, the ratio of each of the molecules should be used, for example, (H2O)0.5(D2O)0.5.

3. Use the input combo box to choose between molar volume or mass density and then type in an input value.

4. Press Tab button or click out to perform the calculation.
