First, we calculate the molar mass of CO₂ as 12 + 32 = 44 g/mol. So, 22 grams is exactly 0.5 moles. Using Avogadro's number, that gives 0.5 × 6.022 × 10²³ molecules.
But honestly, while I know this, my mind is half on my physics numericals and half on Appa’s loan payment due next week. The pressure of these marks feels heavier than any molar mass. Still, like my coach says, one step at a time. Okay, let's go!
