2. A cleaning solution calls for a 15% (v/v) mixture of cleaner in water. How much cleaner and water are necessary to prepare 4.0 L of the solution? EXPRESSING HOW MUCH IN SOLUTION Molarity (M) mass of solute mass %= x 100% moles solute mass of solution M = liters solution volume of solute volume %= x 100% volume of solution When tiny amounts present 1 ppm - 1 mg/L 1 ppb = 1 ug/L mass of solute x 10 mass of solution* mass of solute ppb = 10° mass of solution ppm Exam 4 CHE 110 Fall 2020 10 3. Zinc acid react according Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g). What volume, in L, of 0.100 M hydrochloric acid will react with 35.5g of zinc? hydr following balanced equation: 4. A 1.5 M aq. NHẠCI solution and a 1.25M aq. LizSO4 solution are separated by a semipermeable membrane. Will the water flow toward the NH,Cl solution, or the LizSO4 solution? How do you know? 5. We have a saturated solution of CaCl2. Can we also say that it is a concentrated solution? Explain your answer.
