Best Answer

5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.

So the mass concentration = 5/80 = 100*5/80% = 6.25%

5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.

So the mass concentration = 5/80 = 100*5/80% = 6.25%

5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.

So the mass concentration = 5/80 = 100*5/80% = 6.25%

5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.

So the mass concentration = 5/80 = 100*5/80% = 6.25%

This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.

concentration?

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.

Molar concentration is the number of moles of a substance per litre. One litre of pure water is 1kg, or 1,000 grams. The molecular mass of water is approximately 18 grams per mole. Therefore, there are 1,000/18 = 55.56 mole of water in a litre of water, giving a concentration of 55.56 M.

Supposed 100 ml water has a mass of 99.8 grams (its density at 20oC being 998 g/dm³):Then:100% * (5 g) / [99.8 g + 5 g] = 4.77 % salt
