Mole to Gram Stoichiometry

Determine how many grams are in 0.36 moles of CCl₄.

• 150 g

• 55 g

• 0.0023 g

• 2.2 g

The formula to relate mass, mole and molar mass

• mole = molar mass/ mass

• mole = mass/molar mass

• mass=mole/ molar mass

• molar mass = mole/ mass

Find the mole of 4g of NaOH.

• mole =4/(23+16+1)

• mole = 4x(23+16+1)

• mole = (23+16+1)/4

• mle = (23+16+1)x4

Find the mass of 0.5 mol oxygen gas, (O₂)

• 0.5 = mass/ (16)

• 0.5 = mass/ (16x2)

• 0.5 = mass x (16)

• 0.5 = mass x(16x2)
