1 tablet with 800 mg of ibuprofen has the same amount of active ingredient as 4 tablets with 200 mg of ibuprofen each (200 mg is a pretty common dosage for over-the-counter ibuprofen tablets).
100mg.
C13H18O2 500 mg ibuprofen (1 gram/1000 mg)(1 mole ibuprofen/206.274 grams)(13 mole C/1 mole ibuprofen)(6.022 X 10^23/1 mole C) = 1.90 X 10^22 atoms of carbon in that mass ibuprofen
1 MG
175 mg
1000 mcg = 1 mg so 150mcg is 0.150 mg (150 microgram (mcg or µg) = 0.15 milligram (mg)). So 1 tablet is more than enough and will give you more than 150mcg. You would need to crush the tablet and measure out 0.150mg of active drug on a scale.

To convert micrograms (mcg) to milligrams (mg), you divide by 1,000, since 1 mg equals 1,000 mcg. Therefore, 50 mcg is equivalent to 0.05 mg. Since each tablet is 0.1 mg, you would need 0.05 mg / 0.1 mg per tablet = 0.5 tablets. Thus, it would take half of a 0.1 mg tablet to equal 50 mcg.
To determine how many tablets to give the patient, divide the total dosage required (1 gram) by the dosage per tablet (250 mg). Since 1 gram is equal to 1000 mg, you would calculate 1000 mg ÷ 250 mg per tablet = 4 tablets. Therefore, you will give the patient 4 tablets.
The weight of a tablet can vary depending on the size and the active ingredients. However, most tablets weigh between 500 mg to 1 gram.
Forty (40) 500mcg tablets are required to equal 20mg
One-half (1/2) tablet. 0.25 mg is equal to 250 mcg. So if you had a 500mcg tablet you would only need to take one-half (1/2) tablet for the correct dose.
