Calculate Mass in Grams from Molecules



Formula

The formula to calculate the mass in grams from molecules is:

\[ m = \frac{N \cdot M}{N_A} \]

Where:

Example

Let's say the number of molecules (N) is \( 1 \times 10^{24} \) and the molar mass (M) is 18 g/mol. The mass would be calculated as follows:

\[ m = \frac{1 \times 10^{24} \cdot 18}{6.02214076 \times 10^{23}} \approx 29.88 \text{ grams} \]

So, the mass is approximately 29.88 grams.

What is a Molecule?

A molecule is the smallest unit of a chemical compound that can exist. It is composed of two or more atoms that are chemically bonded together. Molecules are the building blocks of matter and can vary greatly in size and complexity. They can consist of atoms of the same element, such as O2 (oxygen gas), or different elements, such as H2O (water). Molecules are involved in chemical reactions and are essential to the structure and function of living organisms.
