Unit 11 BR #3: Molarity Calculations

Front

What is molarity?

Back

Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution.

Front

How do you calculate moles from molarity and volume?

Back

Moles = Molarity (M) × Volume (L).

Front

What is the formula to find the mass of a solute in a solution?

Back

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

Front

How do you convert grams to moles?

Back

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

Front

What is the molar mass of sucrose (C12H22O11)?

Back

The molar mass of sucrose is approximately 342.3 g/mol.

Front

How do you find the volume of a solution from moles and molarity?

Back

Volume (L) = Moles / Molarity (M).

Front

What is the molar mass of calcium fluoride (CaF2)?

Back

The molar mass of CaF2 is approximately 78.08 g/mol.

Front

How do you calculate the molarity of a solution?

Back

Molarity (M) = Moles of solute / Volume of solution (L).

Front

What is the molar mass of magnesium oxide (MgO)?

Back

The molar mass of MgO is approximately 40.31 g/mol.

Front

If you have 1.3 moles of NaCl in 2.0 L of solution, what is the molarity?

Back

Molarity = 1.3 mol / 2.0 L = 0.65 M.
