<span>The 80 ml solution has (.04)(80) ml of the medicine, or 3.3 ml of medicine.The pharmacist adds V ml of 7% solution, or .07V ml of medicine. The total amoune of medicine is (.07V + 3.2) mg.
The total volume of solution is (V + 80) ml, so
(.07V + 3.2) / (V + 80) = .05. Solve for V.</span>
<em>D</em> = 1.59 g/mL = 1.59 kg/L
Mass of CCl₄ = 703.55 g – 346.8 g = 357.75 g
<em>D</em> = mass/volume = 357.75 g/225 mL = 1.59 g/mL
(1.59 g/1 mL) × (1 kg/1000 g) × (1000 mL/1 L) = 1.59 kg/L
