Vedclass · Answer

(A) $1$. Calculate the molar mass of glycerine $(C_3H_8O_3)$: $(3 	imes 12) + (8 	imes 1) + (3 	imes 16) = 36 + 8 + 48 = 92 \ g/mol$. $2$. Calculate the moles of glycerine: $n_{	ext{glycerine}} = \frac{46 \ g}{92 \ g/mol} = 0.5 \ mol$. $3$. Calculate the moles of water $(H_2O)$: $n_{	ext{water}} = \frac{36 \ g}{18 \ g/mol} = 2.0 \ mol$. $4$. Calculate the total moles in the solution: $n_{	ext{total}} = 0.5 + 2.0 = 2.5 \ mol$. $5$. Calculate the mole fraction of glycerine $(X_{	ext{glycerine}})$: $X_{	ext{glycerine}} = \frac{n_{	ext{glycerine}}}{n_{	ext{total}}} = \frac{0.5}{2.5} = 0.2$.

Find out the mole fraction of glycerine in a solution containing $46 \ g$ of glycerine $(C_3H_8O_3)$ and $36 \ g$ of water $(H_2O)$.
