This would be considered a saturated solution if all 25g of KCl are completely dissolved in the 100g of water at 30 degrees Celsius.
The parts per million (ppm) of solute in a solution can be determined using the formula: ppm = (mass of solute/mass of solution) x 1,000,000. In this case, the mass of sodium chloride is 25g and the mass of the solution is 200g (25g NaCl + 200g water = 225g). Therefore, the ppm of sodium chloride in the solution is (25g/225g) x 1,000,000 = 111,111 ppm.
Really easy: put more solute in the solvent than the solvent can hold.If you're trying to make a saline solution with sediment and water can hold 25g/liter of salt (I just picked a number, sorry), put 50g/liter of salt in the water. 25g will dissolve, the rest will sink to the bottom.
The total mass of a mixture of 25g of salt and 125g of water is simply the sum of the individual masses. Therefore, the total mass is 25g + 125g = 150g.
Phthalic acid will dissolve 18g of per 100mL of boiling water. (25g/18g) x 100mL = 138.89mL of boiling water is needed to dissolve 25g of phthalic acid.
If it's a 4% solution by mass, you want 4.167g of acetic acid (25g/6)
if the concentration of sugar solution of volume of 360 cm3 cube is 0.785 mol/ dm3 has the mass of 25g of sugar present in the solution. work out for the mole of the sugar content in the solution.
To calculate the volume of intralipid needed, first convert 25g to ml using the density of lipids, which is around 0.9 g/ml. This means 25g is approximately 27.78 ml. Since the intralipid solution is 20%, the rest of the volume should be saline (0.9% solution) – so divide the required volume (27.78 ml) by 0.2 to get the total volume of 20% intralipid needed, which would be 138.9 ml.
1 ml of water masses 1 g, so the answer is 25 ml. ■
