A certain medication recommends that each day a person be given 8 mg for every 100 lbs of weight. If 10,000 people take this medication each day and their average weight is 180 lbs, how many kilograms of this drug are used daily?

Total Mass of daily drug used = 144 Kg

Explanation:

Total weight of the individuals =

180lbs * 10000 = 1.8 * 10^6 lbs

Since the drug is to be given 8 mg for every 100 lbs;

number of 8 mg doses = 1.8 * 10^6 / 100 = 1.8 * 10^4 doses

Total mass of the doses = 1.8 * 10^4 * 8 mg = 1.44 * 10^5 mg.

We divide the value above by 1000 to convert to Kg.

Therefore, total daily mass of drug used = (1.44 * 10^5)/1000 = 144 Kg

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
