In 40.32 kg of NaHCO₃, there are 2.890 × 10²⁶ formula units of NaHCO₃.
<h3>What is a formula unit?</h3>
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.

Because supergiants are so massive, the core temperature gets much hotter than in giants, so supergiants can fuse elements heavier than hydrogen and helium. But to support their tremendous mass, supergiants burn up their fuel much more quickly.
The balanced equation would be:
2HCl + Mg(HCO3)2 —> MgCl2 + 2CO2 + 2H2O
The answer is yes I believe so.
