What is a formula unit?

A formula unit is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations.

• Step 1: Convert 40.32 kg to g.

We will use the conversion factor 1 kg = 1000 g.

40.32 kg × (1000 g/1 kg) = 4.032 × 10⁴ g

• Step 2: Convert 4.032 × 10⁴ g to moles.

We will use the molar mass of NaHCO₃ as the conversion factor.

4.032 × 10⁴ g × (1 mol/84.01 g) = 479.9 mol

• Step 3: Convert 479.9 moles to formula units (fu).

We will use Avogadro's number as the conversion factor.

479.9 mol × (6.022 × 10²³ fu/1 mol) = 2.890 × 10²⁶ fu

In 40.32 kg of NaHCO₃, there are 2.890 × 10²⁶ formula units of NaHCO₃.
