What is the weight/volume percent concentration in a suspension of Amoxil that contains 50 mg/mL? b. If the typical pediatric dose is 25 mg/kg per day, what volume of drug is given for a 15-kg child?

For questions #14-16, you should do your work on a separate piece of paper and then upload it. You should use the GUESS Method of solving for each problem. Also, you have a choice. You can complete both #14 & #15 which are single step question or do the extension problem which is a 2 step problem instead of 14 & 15. You must complete #16. Equations Q = mcAT Q = ±mLf Q = ±mLv Values for Water Clice) = 2.06 J/g°C C(water) = 4.186 J/g°C C(steam) = 1.87 J/g°C Lf (water) = 333 J/g Lv (water) = 2,260 J/g %3D G- S- U- E- S- #14. Calculate the energy required to heat 12.5 g of water from a temperature of 42.2°C to 52.3°C. #15. How much thermal energy is needed in order to turn 15.7 grams of water into ice? Extension: We start with 23.2 grams of ice at 0°C and add heat to the ice. The ice completely melts and then is heated until it reaches 45.3°C. How much energy is added in total? #16. 12.0 g of a metal absorbs 317 J when it is heated from 38.2°C to 82.7°C. What is the specific heat of the…
