Video transcript

Hi everyone for this problem. It reads a glucose solution is prepared by dissolving 9.54 g of glucose in 100 and 68 g of water at 25 degrees Celsius. What is the concentration of the solution in mass? Percent. So our goal here is to express our answer and mass percent. So let's just recall what is mass percent. Mass percent is equal to the mass of our salute over the mass of our solution Times 100%. So both of these values are given in the problem. So we just need to plug it in. Okay? So for our salute, our salute is the glucose and we know we have 9.45 g of that. Our solution is going to be the combination of our salute and our solvent. Our salute is the glucose and our solvent is the water. So 9.545 g plus 100 and 68 g times 100%. So that gives us a final answer of 5.32%. Okay, and this is going to be our answer. That's the end of this problem. I hope this was helpful

Suppose that one wishes to use reverse osmosis to reduce the salt content of brackish water containing 0.22 M total salt concentration to a value of 0.01 M, thus render- ing it usable for human consumption. What is the mini- mum pressure that needs to be applied in the permeators (Figure 18.20) to achieve this goal, assuming that the oper- ation occurs at 298 K? (Hint: Refer to Section 13.5.)
