Multiple Choice

Below is a diagram representing a solvent A(l) in a 1-L beaker,and a solute X dissolved in the solvent.Solvent A has a density of 0.8 g/mL,and a molar mass of 40 g/mol. Solute X has a molar mass of 30 g/mol.Each circle of X represents 1 mol of X.Assume that the solute addition does not significantly change the volume of liquid in the beaker. $Below is a diagram representing a solvent A(l) in a 1-L beaker,and a solute X dissolved in the solvent.Solvent A has a density of 0.8 g/mL,and a molar mass of 40 g/mol.
