Calculate Density from Molecular Weight





Formula

To calculate the Density from Molecular Weight (\(D\)):

\[ D = \frac{P \times MW}{R \times T} \]

What is Density from Molecular Weight?

Density from molecular weight is a calculation used to determine the density of a gas based on its molecular weight, pressure, and temperature. This is particularly useful in fields such as chemistry and engineering where understanding the properties of gases is essential.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ D = \frac{101325 \times 0.02897}{8.314 \times 298} \approx 1.18 \text{ kg/m³} \]

The density is approximately 1.18 kg/m³.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ D = \frac{202650 \times 0.04401}{8.314 \times 298} \approx 3.00 \text{ kg/m³} \]

The density is approximately 3.00 kg/m³.
