Why do you add the mass of water to the mass of salt dissolved in it to find the mass of the solution?
Nope. The volume does not change but the density of the mixture increases. No, the volume of water is straight forward to measure but salt as a solid composed of small crystals has an aparent volume wich includes many voids filled with air. Assuming you have measured properly the two components volumes adding them will provide you with what is known as ideal volume, but reality deviates from this linear additive values. Especially with electrolytes such as sodium chloride the final volume differs from ideal addition values expected.The topic has been extensively studied and explained by science, look for partial molar volumes concept and equations in basic physical chemistry textbooks. Remember that mass is conservative and that density is defined as mass per unit volume, say grams per milliliter. It is right to say that density changes ( measuring densities is the way to construct partial molar volumes graphs), since mass is conservative the only way to get density changes is by increasing or decreasing volumes. Solutions are classified as ideal (additive volumes) or non ideal (non additive volumes). Hope this solves your question.

Is the mass of an antacid tablet conserved after they are dissolved?
Yes, the mass of an antacid tablet is conserved after it dissolves in a solution. According to the law of conservation of mass, the total mass of the reactants (the antacid tablet and water) equals the total mass of the products (the dissolved substances in the solution). While the tablet may change form and release ions into the solution, the overall mass remains the same.
Does dissolved sugar and mass to water?
Sugars are carbohydrates and simple sugars are monosaccharides such as glucose, fructose etc with the general formula C6H12O6. When dissolved in water, these molecules do not break further and hence the mass remains the same.
A 20.0-g sample of sugar is dissolved in 59.8 g of water. What is the concentration of the solution?
25 percent by mass
What is the mass of 24g sugar completely dissolved in 576g water?
When 24g of sugar dissolves in 576g of water, the total mass of the solution remains at 600g (24g + 576g). The mass of the sugar does not change when it dissolves, it simply disperses throughout the water.
When sugar is dissolved in water What about its weight?
The mass of both solute and solvent are conserved (sugar water weighs the same as the sugar plus the water), the volume of the solution increases less than the dry volume of the sugar, so the density of the solution is higher than water.
What is the mass of the solution when 1 pound of salt is dissolved into 20 pounds of water?
21 Pounds.
What is the mass of the solution when 1 pound of salt is dissolved in to 20 pounds of water?
21 pounds
What ids the total mass of the solution when 5 gramme of salt desolved in 100 gramme of water?
The total mass of the solution is 105 grams, which is the sum of the mass of the salt (5 grams) and the mass of the water (100 grams). The mass of the solute (salt) and the solvent (water) are additive in a solution.
Is the mass of an antacid tablet conserved after they are dissolved?
Yes, the mass of an antacid tablet is conserved after it dissolves in a solution. According to the law of conservation of mass, the total mass of the reactants (the antacid tablet and water) equals the total mass of the products (the dissolved substances in the solution). While the tablet may change form and release ions into the solution, the overall mass remains the same.
What is the percentage by mass of 5grams of iron sulfate dissolved in 75grams of water?
The mass of the solution is 5g (iron sulfate) + 75g (water) = 80g. Therefore, the percentage by mass of iron sulfate in the solution is (5g / 80g) * 100% = 6.25%.
Does dissolved sugar and mass to water?

A sugar solution of 35.8g sugar and 125.35g of water. what is the percent by mass of the sugar and the percent by mass of the water in the solution?
add 35.8g sugar to 125.35g of water this = 100% of the solution. then divide 35.8g of sugar by the whole solution and multiply by 100 to get the percentage (35.8)/ (125.35 + 35.8)= .222 * 100= 22.2% sugar is 22.2% of the solution. Do the same for the water switch 35.8 by 125.35
What is the mass of 40g of sugar water?
The mass of the sugar water would still be 40g. When a solute, like sugar, is dissolved in a solvent, like water, the mass of the solution remains the same as the individual components do not change their mass through dissolution.
If you have 1000 gram of a 10 -percent solution of sugar water how much sugar is dissolved in the solution?
The mass of sugar is 100 g.
What is the mass of 24g sugar completely dissolved in 576g water?
