Mole Conversions (Setup)

Front

What is a mole?

Back

A standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.

Front

What is Avogadro's number?

Back

Avogadro's number is 6.022 x 10^23, which is the number of molecules in one mole of a substance.

Front

How do you convert moles to grams?

Back

To convert moles to grams, use the formula: grams = moles x molar mass (g/mol).

Front

How do you convert grams to moles?

Back

To convert grams to moles, use the formula: moles = grams / molar mass (g/mol).

Front

What is the molar mass of Helium (He)?

Back

The molar mass of Helium (He) is approximately 4.003 g/mol.

Front

What is the conversion factor for moles to molecules?

Back

1 mole = 6.022 x 10^23 molecules.

Front

What is the conversion factor for moles to liters (at STP)?

Back

1 mole = 22.4 liters (at standard temperature and pressure).

Front

If you have 12 moles of NaCl, how do you convert it to grams?

Back

Use the molar mass of NaCl (approximately 58.44 g/mol): grams = 12 moles x 58.44 g/mol.

Front

How many moles are in 32.07 g of Sulfur (S)?

Back

Use the molar mass of Sulfur (approximately 32.07 g/mol): moles = 32.07 g / 32.07 g/mol = 1 mole.

Front

What is the formula to find the number of molecules in a given number of moles?

Back

Number of molecules = moles x Avogadro's number (6.022 x 10^23).
