The actual mass of a molecule of carbon dioxide is

1.	The actual mass of a molecule of carbon dioxide is
Answer» $7.30\times 10^{-23}$ Answer : The actual mass of a molecule of CARBON dioxide is, gram. Explanation : According to AVOGADRO's law, 1 mole of EVERY substance weighs equal to the molecular mass and contains Avogadro's number $6.023\times 10^{23}$ of particles. To calculate the moles, we use the EQUATION: $\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadro's number}}$ $\text{Number of moles}=\frac{1}{6.023\times 10^{23}}=0.17\times 10^{-23}moles$ As, 1 mole of $CO_2$ molecule weighs = 44 g $0.17\times 10^{-23}$ moles of $CO_2$ molecule weighs = $\frac{44}{1}\times 0.17\times 10^{-23}=7.30\times 10^{-23}g$ $7.30\times 10^{-23}$ Therefore, the mass of a molecule of carbon dioxide is, gram.
