$Molarity = \frac{Moles of solute}{Volume of solution} = 9.45 \cdot m o l \cdot L^{- 1}$ $"Molarity"="Moles of solute"/"Volume of solution"=9.45*mol*L^-1$

Explanation:

Now $ρ_{toluene} = 0.871 \cdot g \cdot m L^{- 1}$ $rho_"toluene"=0.871*g*mL^-1$ ...and thus...

$Concentration = \frac{Moles of toluene}{Volume of toluene}$ $"Concentration"="Moles of toluene"/"Volume of toluene"$

And we work from a $1 \cdot m L$ $1*mL$ volume of toluene...

$\frac{\frac{0.871 \cdot g}{92.14 \cdot g \cdot m o l^{- 1}}}{1 \cdot m L \times 10^{- 3} \cdot L \cdot m L^{- 1}} = 9.45 \cdot m o l \cdot L^{- 1}$ $((0.871*g)/(92.14*g*mol^-1))/(1*mLxx10^-3*L*mL^-1)=9.45*mol*L^-1$
