It remains constant since no liquid or solid escapes. However, it can also be argued that the total mass drops, since the surface of the solute evaporates, reducing the amount of substance in the solution.
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.
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.
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.
Molality is to moles of solute over mass of solvent in kilograms.
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.
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.
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.
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.
Let’s solve this step-by-step carefully. Given: Mass of solute = **62 g** Mass of solvent (water) = **125 g = 0.125 kg** Molality (m) = **5.3 m** Formula for molality: [ m = \frac{\text{moles of solute}}{\text{kg of solvent}} ] Rearrange for moles of solute: [ \text{moles of solute} = m \times \text{kg of solvent} ] [ \text{moles of solute} = 5.3 \times 0.125 = 0.6625 \text{ mol} ] Molar mass formula: [ \text{Molar mass} = \frac{\text{mass of solute (g)}}{\text{moles of solute}} ] [ \text{Molar mass} = \frac{62}{0.6625} \approx 93.6 \text{ g/mol} ] ✅ **Final Answer:** [ \boxed{Molar\ mass = 93.6\ \text{g/mol}} ] Buy Verified TikTok Accounts Buy Verified TikTok Accounts can be incredibly valuable for creators and brands.

To calculate the molality (m) of a solution, you need to know the number of moles of solute and the mass of the solvent in kilograms. If you dissolve 2 moles of solute in a specific mass of solvent, you can use the formula: ( m = \frac{\text{moles of solute}}{\text{mass of solvent (kg)}} ). Without the mass of the solvent, the molality cannot be determined. Please provide the mass of the solvent for a complete answer.
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.
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} ]
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.
Molality is to moles of solute over mass of solvent in kilograms.
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.
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.
