Solvents $A$ and $B$ are completely immiscible. Solute $S$ is soluble in both these solvents. $100\: g$ of $S$ was added to a container which has $2\: kg$ each of $A$ and $B$. The solute is $1.5$ times more soluble in solvent $A$ than in solvent $B$. The mixture was agitated thoroughly and allowed to reach equilibrium. Assuming that the solute has completely dissolved, the amount of solute in solvent $A$ phase is _____________ $g$.
