When medications are given to a patient in an IV, the IV solution must be equivalent (isotonic) to blood plasma. If not, the IV solution added to patient can cause cells to shrink or expand as water tries to equilibrate the interior of each cell with the blood. Correct medication doses (called "compounding") must be computed by pharmacists to create isotonic solutions. The most accurate approach uses freezing point depression differences to calculate the correct salt concentration needed. Blood plasma has a freezing point depression of -0.52 so the compounds in solution must add up to the 0.52 total. Assume the density of solution is 1.0(g)/(m)L. a. The freezing point depression of a 1.0%(w)/(v) morphine sulfate solution was measured as 0.1382\deg C. Calculate the approximate molar mass of morphine sulfate if the van't Hoff factor is 2.85 . Ans:3842gtmol 387.5(g)/(m)ol

Let a subset W be the set of all vectors in $\mathbb{R}^4$ such that $x_1 + 3x_2 + 5x_3 + 7x_4$ a subspace of $\mathbb{R}^4$. According to the theorem of conditions for a subspace, the nonempty subset two conditions: (i) If u and v are vectors in W, then u + v is also in W. (ii) If u is in W and c is a scalar, then the vector cu is also in W.

Select all that apply about stochastic gradient descent (SGD). Question 10 options: A stochastic subgradient is a randomized choice of a vector in each step. SGD may be trapped in a local minimum. SGD reduces computation in finding the optimal solution for the objective function. SGD is iterative in operation.
