How do you convert Avogadro’s number to grams?

Avogadro’s number, denoted as �ANA​, is a fundamental constant in chemistry and physics. It represents the number of atoms, molecules, or particles in one mole of a substance. Its value is approximately 6.022×10236.022×1023 per mole.

To convert Avogadro’s number to grams, you need to specify the substance for which you want to calculate the mass. The molar mass of the substance, denoted as �M and measured in grams per mole (g/mol), is required.

The formula to convert Avogadro’s number to grams is as follows:

Mass (g)=�A×�Mass (g)=NA​×M

Where:

• �ANA​ is Avogadro’s number (6.022×10236.022×1023 particles per mole)
• �M is the molar mass of the substance in grams per mole

Here’s an example:

Let’s say we want to convert Avogadro’s number to grams for oxygen (O2). The molar mass of oxygen is approximately 32.00 g/mol.

Mass (g)=(6.022×1023)×(32.00 g/mol)Mass (g)=(6.022×1023)×(32.00g/mol) Mass (g)=1.925×1025 gMass (g)=1.925×1025g

Therefore, Avogadro’s number for oxygen is approximately equal to 1.925 × 10^25 grams.
