Key Questions
How do you calculate the percentage of salt in a solution?Salt is the solute (the dissolving substance), and water is the solvent (the substance that dissolves another to create a solution). To make a salt solution by weight percent (w/v), you apply the formula w/v = (mass of solute ÷ volume of solution) × 100.
When 5 gram of sugar is dissolved in 25 gram of solvent the concentration of the sugar will be W W?Explanation: The mass by volume percentage of 250 ml of a solution containing 5 g of sugar is 2%.
What is the percentage mass by mass amount of salt in the solution containing 5 grams of a salt dissolved in 25 grams of water?Loved by our community
Total mass = 0.5+25=25.5%=0.5/25.5+×100=1.9607%. The value can be calculated with the amount of salt in that solution that gives answers percentage with dissolved in 25g of water.
What is the percentage by mass of 50g salt dissolve in a 500g of water?Mass by vol % = 50 g / 500 ml x 100. Mass by vol % = 0.1 x 100 = 10 %
