Answer

131.64 g CO_2 Explanation 1. Calculate moles of CO_2 Use the formula: **moles = \frac{\text{number of molecules}}{\text{Avogadro's number}}**. Substitute the values: \frac{1.8 \times 10^{24}}{6.02 \times 10^{23}}. 2. Calculate mass of CO_2 Use the formula: **mass = moles \times molar mass**. Substitute the values: (\frac{1.8 \times 10^{24}}{6.02 \times 10^{23}}) \times 44.01.

Explanation

1. Calculate moles of $CO_2$<br /> Use the formula: **moles = \frac{\text{number of molecules}}{\text{Avogadro's number}}**. Substitute the values: $\frac{1.8 \times 10^{24}}{6.02 \times 10^{23}}$.<br />2. Calculate mass of $CO_2$<br /> Use the formula: **mass = moles \times molar mass**. Substitute the values: $(\frac{1.8 \times 10^{24}}{6.02 \times 10^{23}}) \times 44.01$.
