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

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

the right answer is c i just did the question.
