To calculate the mass of a solvent in a mixture, you will need the volume of the mixture and the molality of the solvent. You can use the formula: mass = volume x molality.
Molality is the number of moles of solute per kilogram of solvent, while molarity is the number of moles of solute per liter of solution. Molality takes into account the mass of the solvent, while molarity does not.
No, you must use consistent units of volume and molality in the mass calculation. For example, if the volume is in milliliters, the molality should be in moles per kilogram.
Temperature does not directly affect the mass calculation, but it does affect the density of the solvent, which can then impact the volume measurement. It is important to use the correct volume and molality at the same temperature to ensure accuracy.
No, the mass of the solvent can only be calculated if the volume and molality of the solvent are known. If the solute is unknown, you will need to determine its mass first before calculating the mass of the solvent.
