How many moles are in 24 g of CO2? The relative formula mass is 44.

Explanation:
The calculation uses the key idea that the amount of substance in moles equals mass divided by molar mass. For CO2, the molar mass is 44 g per mole. So, 24 g of CO2 corresponds to 24 ÷ 44 = 0.545... moles. This gives about 0.545 moles (often rounded to 0.55 moles when sticking to two significant figures). That’s why this result is the correct one.
