PRE-LAB EXERCISE The hydrogen peroxide solution that you are using in this experiment is labeled as a 3% solution, so 3% of the mass of the mixture is H2O2. However, to complete the calculations, the concentration must be in molarity (mol/L). Calculate the molarity of solutions that are 3.0% and 1.5% H2O2 by mass solution (hint: assume a volume of solution such as 100 mL or 1 L and work from there. The density of the solution is very near that of water: 1.00 g/mL) Concentration in Molarity (mol/L) Concentration in Percent by mass (%) 3.0% H2O2 1.5% H2O2

Part B - Ideal op amp circuits with a voltage source: part 2 For the circuit shown (Figure 1), determine the range (i.e., maximum and minimum values) of \( V_{2} \) so that the op amp operates in the linear region. Assume that \( R_{1}=6 \mathrm{k} \Omega, R_{2}=6 \mathrm{k} \Omega, R_{3}=35 \mathrm{k} \Omega \), and \( V_{c c}=15 \bar{V} \). Express your Part B - Ideal op amp circuits with a voltage source: part 2 For the circuit shown (Figure 1), determine the range (i.e., maximum and minimum values) of V2​ so that the op amp operates in the linear region. Assume that R1​=6kΩ,R2​=6kΩ,R3​=35kΩ, and Vcc​=15Vˉ. Express your answer in volts to two significant figures separated by a comma.

Photon Technologies, Inc., a manufacturer of batteries for mobile phones, signed a contract with a large electronics manufacturer to produce three models of lithium-ion battery packs for a new line of phones. The contract calls for the following: Mexico plant. The cost of shipping from the Philippines plant is $0.15 per unit, and the cost of shipping from the Mexico plant is $D.12 per unit. constraint is one, enter "1". If the amount is zerp, enter "O". Let P1= number of PT-100 battery packs produced at the Philippines plant P2 = number of PT-200 battery packs produced at the Philippines plant P3 = number of PT-300 battery packs produced at the Philippines plant M1 = number of PT-100 battery packs produced at the Mexico plant M2 = number of PT-200 battery packs produced at the Mexico plant M3 = number of PT-300 battery packs produced at the Mexico plant (b) Solve the linear program developed in part (a), to determine the optimal production plan. If the amount is zero, enter "0". Total Cost =$ If required, round your answer to two decimal digits. At least ← (3) / unit. (d) Use sensitivity analysis to determine how much the production and/or shipping cost per unit would have to change to produce additional units of the PT-200 in the Mexico plant. If required, round your answer to two decimal digits. At least : / unit.
