What is a mole in chemistry?

Back

A mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of substance that contains as many entities (atoms, molecules, etc.) as there are in 12 grams of carbon-12.

Front

How do you convert moles to grams?

Back

To convert moles to grams, use the formula: grams = moles × molar mass.

Front

What is the molar mass of a substance?

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.

Calculate the molar mass of water (H2O).

Back

The molar mass of water is 18.015 g/mol (2 × 1.008 for H + 16.00 for O).

Front

How do you convert grams to moles?

Back

To convert grams to moles, use the formula: moles = grams / molar mass.

Front

What is the molar mass of carbon dioxide (CO2)?

Back

The molar mass of carbon dioxide is 44.01 g/mol (12.01 for C + 2 × 16.00 for O).

Front

If you have 100 grams of NaCl, how many moles do you have?

Back

Molar mass of NaCl is 58.44 g/mol. Moles = 100 g / 58.44 g/mol = 1.71 mol.

Front

What is the formula to find the number of moles from mass and molar mass?

Back

Moles = Mass (g) / Molar Mass (g/mol).

Front

How many grams are in 2.5 moles of glucose (C6H12O6)?

Back

Molar mass of glucose is 180.18 g/mol. Grams = 2.5 moles × 180.18 g/mol = 450.45 g.

What is the relationship between moles and molecules?

Back

1 mole of any substance contains 6.022 × 10^23 entities (Avogadro's number).
