How much water must be evaporated from 240 gallons of a 3 percent salt solution to produce a 5 percent solution?
96
How much of a 6 percent solution and a 12 percent solution would use to make 240 milliliters of a 7 percent electrolyte?
x+y = 240 0.06x + 0.12y =240(0.07) = 16.8 0.06x + 0.12(240 - x) = 16.8 0.06x + 28.8 - 0.12x = 16.8 -0.06x = -12 x = 200.......6% solution y = 40........12% solution
A solution contains 1.20 g of CaCl2 and 240 mL of solution what is the percent w-v concentration of the solution?
To calculate the percent weight/volume (w/v) concentration, divide the mass of solute (CaCl2) by the volume of solution and multiply by 100. First, convert 240 mL to L by dividing by 1000 (240 mL = 0.24 L). The concentration is (1.20 g / 0.24 L) x 100 = 5% w/v.

A solution contains 1.20 g of CaCl2 and 240 mL of solution what is the percent w-w concentration of the solution if the solution has a density of 1.13 g-mL?
First, find the total mass of the solution by multiplying the density (1.13 g/mL) by the volume (240 mL). This gives 271.2 g. Now, calculate the percent concentration of CaCl2 in the solution by dividing the mass of CaCl2 (1.20 g) by the total mass of the solution (271.2 g) and multiplying by 100. The percent w/w concentration of the solution is approximately 0.44%.
