Problem- For Acute Otitis Media (Ear Infection), Children 2 months to 6 years old should be given 85 mg of amoxicillin per kilogram of body weight per day, divided into two or three doses and taken for 10 days. For a four year old child weighing 36 lbs, given two doses per day, the amount of amoxicillin in mg per does is:
A. 7.3x10^2 mg
B. 6.8x10^-1 mg
C. 6.9x10^2 mg
D.14x10^2 mg
Please show me how work it out above problem
World energy supplies are often measured in the unit of quadrillion British thermal units (1012 Btu), generally called a "quad." In 2015, world energy consumption is projected to be 5.81 ×1017kJ.
In this experiment you will measure the heat of combustion (delta Hc) of naphthalene. Report the values of the following: Cv, the heat capacity of the system.
One mole of an ideal monoatomic gas initially at 300 K is expanded from an initial pressure of 10 atm to a final pressure of 1 atm. The molar heat capacity for constant volume for the gas is 32VCR=. Calculate dU, dH, q, w, and the final temperatur..
