WebA nurse needs 50 mL of a 16% salt solution for a patient. She can only find a 13% salt solution and an 18% salt solution in the supply room. How many millimeters of the 13% solution should be mixed with the 18% solution to produce the desired amount of the 16% solution?-----Equation:: salt + salt = salt 0.13x + 0.18(50-x) = 0.16*50----- WebAnswer (1 of 8): As concentration varies with volume of solvent but amount is unchanged As water evaporates concentration varies but amount of salt dont vary So you may understand what i have done in photo disgrace definition english

WebInitial Data. Concentration Before Dilution (C1) %. Volume Before Dilution (V1) Concentration After Dilution (C2) %. Volume After Dilution (V2) Volume Of Solvent Needed For Dilution (V) WebAnswer (1 of 4): The key is to recognize the percentage concentration is mass of solute divided by mass of solution, not the original solvent. If you add x grams of salt, the solution has a mass of 250 g + x x/(250 g + x) = 0.15 x = 250 g * 0.15/0.85 = 44.12 g (rounded) Check 44.12/294.12 = 0...
