Apatient needs to take 875 mg of ibuprofen twice daily. the pills in the bottle are each 250. mg. how many pills does the patient need to take each time she wants the 875 mg dosage? assume that these pills are scored and can be cut in half if necessary.

The patient needs to take 3 and 1/2 pills to get the required 875 mg dosage. The patient, therefore, will have to take a total of 7 pills daily.

Further Explanation

This problem can be quickly solved using dimensional analysis. Dimensional analysis is a method of solving problems using the known units of measurements of the quantities given in a problem. The steps include:

STEP 1: Sorting the given in the problem gives the required conversion factors:

1 pill = 250. mg of ibuprofen

1 dose = 875 mg of ibuprofen

STEP 2: Setting up the dimensional analysis to get the equivalent number of pills of 875 mg:

The patient will need to take 3 and a half pills twice a day to get the daily recommended dosage (875 mg) of ibuprofen.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
