How is massed conserved when adding a solute to a solvent?
If you weigh the solute, and then weigh the solvent, and then add the solute to the solvent and weigh the solution, you will find that the sum of the weights of the solute and solvent is equal to the weight of the resulting solution. So mass is conserved.
What is the molar mass of a solute if 62 g of the solute in 125g of water produce a 5.3m solution?
First, calculate the mass of the solvent (water) using the total mass of the solution. Mass of solvent = Total mass of solution - Mass of solute. Then, convert the mass of the solute into moles using its molar mass. Finally, calculate the molar mass of the solute using the moles of solute and the mass of the solute. molar mass = Mass of solute (g) / Moles of solute.
What are two conditions that determine the mass of solute that will dissolve in a given mass of solvent?
The temperature: Increasing temperature makes the particles move faster. Heat energy is transferred by the movement of the particles. Because the solvent particles are moving faster, they bump into the solute.Stirring: Moves all the particles around do the solvent particles bump into the solute particles.
Molarity is to moles of solute over liters of solution as molality is to?
Molality is to moles of solute over mass of solvent in kilograms.
What happens to volume and mass when dissolving?
When dissolving a substance in a solvent, the volume of the solution increases because the two substances combine. The mass of the solution remains constant, as the total mass before and after dissolving is the same, but it is distributed between the solute and the solvent.
How do the solvent particles break up from the solute?
When a solute dissolves it breaks apart into its individual particles. The solute and solvent particles mix together and become totally mixed up. That's why a solution is a mixture! As the solute and solvent particles become mixed up, no matter is lost. The overall mass stays the same.

If you weigh the solute, and then weigh the solvent, and then add the solute to the solvent and weigh the solution, you will find that the sum of the weights of the solute and solvent is equal to the weight of the resulting solution. So mass is conserved.
How does mass change when solutes are added to solvents?
When solutes are added to a solvent, the overall mass of the solution increases because the mass of the solute is now part of the total mass of the solution. The mass of the solvent remains the same, but the combined mass of the solute and solvent will be greater than the original mass of the solvent alone.
Does the Mass mass percent concentration measures grams of solute per grams of solvent?
No, not exactly.Mass mass percent concentration measures grams of solute per 100 grams of solution (= solvent + solute)Example:58.5 g NaCl (solute) added to941.5 g H2O (solvent) gives you1000.0 g solution of 5.85% NaCl (= 100%*58.5/1000.0),which is about a 1.0 mol/L NaCl solution.
What is the molar mass of a solute if 62 g of the solute in 125g of water produce a 5.3m solution?

Formula for molality?
Molality (m) is calculated by dividing the number of moles of solute by the mass of the solvent in kilograms and is expressed in mol/kg. The formula for molality is: [ molality (m) = \frac{moles\ of\ solute}{mass\ of\ solvent\ in\ kg} ]
Molarity is to moles of solute over liters of solution as molality is to?
Molality is to moles of solute over mass of solvent in kilograms.

How can you dissolve more solid into liquid?
Once you have reached a point where you cannot dissolve any more solute in solvent, you have reached a saturation point of the liquid. Now if you increase the temperature of the solution you will be able to dissolve some more solute. Another way to do this is to greatly increase the volume of solvent.
If something dissolves into something else will it change mass?
The mass of the solution will be equal to the mass of the solute plus the mass of the solvent. However, the total mass does not change.
How do you calculate the molality of a solution?
To calculate the molality of a solution, you divide the moles of solute by the mass of the solvent in kilograms. The formula for molality is: Molality (m) moles of solute / mass of solvent (in kg).
