If the ratio of volumes of the solution of [CoCl2(EtOH)2] and methanol is x: y and the total volume is 4 mL, then the volume that corresponds to the solution of [CoCl2(EtOH)2] = {x/(x + y)}*4 mL and the volume corresponds to methanol = {y/(x + y)}*4 mL
| Ratio of volumes | Volume of the solution of [CoCl2(EtOH)2] (mL) | Volume of methanol (mL) |
| 3: 1 | (3/4)*4 = 3 | 1 |
| 4: 1 | (4/5)*4 = 3.2 | 0.8 |
| 5: 1 | (5/6)*4 = 3.333 | 0.667 |

SOLUTION MAKING in water. Calculate the amount of NaCl you need to weigh out. 1 (a). You need 500mL of 15% (w/v) NaCl 1(b) What approximate volume of water would you dissolve the NaCl in? Please give a range of volumes. 1(c). Assuming that adding the NaCI to your original volume of water caused the volume to increase by 50mL before you added additional water to reach your final volume, what is the DENSITY of your final...
