Question

If 4.4 g of CO2 contains x molecules, what is x? (Molar mass CO2=44 g mol⁻¹)

RankGuru · Accepted Answer

1. **Find Moles of $CO_2$**:
   - $n = \frac{4.4 \ g}{44 \ g/mol} = 0.10 \ mol$.
2. **Calculate Molecules ($x$)**:
   - $x = n 	imes N_A$
   - $x = 0.10 	imes 6.022 	imes 10^{23} = 6.022 	imes 10^{22}$ molecules.
