What is the molar mass of a compound?

Back

The molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in the molecular formula.

Front

How do you convert moles to molecules?

Back

To convert moles to molecules, use Avogadro's number (6.02 x 10^23). The formula is: \( \text{moles} \times \frac{6.02 \times 10^{23} \text{ molecules}}{1 \text{ mole}} \)

What is Avogadro's number?

Back

Avogadro's number is 6.02 x 10^23, which is the number of atoms, ions, or molecules in one mole of a substance.

Front

How do you convert moles to grams?

Back

To convert moles to grams, multiply the number of moles by the molar mass of the substance: \( \text{moles} \times \text{molar mass (g/mol)} \)

Front

What is the formula to find the number of moles from grams?

Back

To find the number of moles from grams, use the formula: \( \text{grams} \div \text{molar mass (g/mol)} \)

Front

What is the molar mass of NaCl?

Back

The molar mass of NaCl (sodium chloride) is approximately 58.44 g/mol.

Front

How do you calculate the molar mass of a compound?

Back

To calculate the molar mass, sum the atomic masses of all elements in the compound's formula, multiplied by their respective quantities.

Front

What is the relationship between moles and molecules?

Back

One mole of any substance contains Avogadro's number (6.02 x 10^23) of molecules.

How many grams are in 1 mole of water (H2O)?

Back

1 mole of water (H2O) has a mass of approximately 18.02 g.

Front

What is the significance of the mole in chemistry?

Back

The mole is a fundamental unit in chemistry that allows chemists to count particles by weighing them.
