Vedclass · Answer

(A) The molar mass of $CO_2$ is $44 \ g/mol$.$4.4 \ g$ of $CO_2$ corresponds to $\frac{4.4 \ g}{44 \ g/mol} = 0.1 \ mol$ of $CO_2$.Each molecule of $CO_2$ contains $2$ oxygen atoms.Therefore,$0.1 \ mol$ of $CO_2$ contains $0.1 	imes 2 = 0.2 \ mol$ of oxygen atoms.The number of oxygen atoms is $0.2 	imes 6.022 	imes 10^{23} \approx 1.2 	imes 10^{23}$ atoms.

The number of oxygen atoms in $4.4 \ g$ of $CO_2$ is approximately ........ $\times 10^{23}$.
