(B) The balanced chemical equation for the combustion of ethane is:$2C_2H_6 + 7O_2 \longrightarrow 4CO_2 + 6H_2O$Alternatively,using $1$ mole of $C_2H_6$:$C_2H_6 + \frac{7}{2} O_2 \longrightarrow 2CO_2 + 3H_2O$From the stoichiometry,$1$ mole of $C_2H_6$ $(30 \ g)$ produces $2$ moles of $CO_2$ ($2 	imes 22.4 \ L$ at $STP$).For $3 \ g$ of $C_2H_6$:$	ext{Moles of } C_2H_6 = \frac{3 \ g}{30 \ g/mol} = 0.1 \ mol$$	ext{Volume of } CO_2 = 0.1 \ mol 	imes 2 	imes 22.4 \ L/mol = 4.48 \ L$.

When $3 \ g$ of $C_2H_6$ is completely burnt,find out the volume of $CO_2$ produced at $STP$ in $L$.
