How many moles of ibuprofen are on 0.5g in ibuprofen?

0.200 *(6.02*1023)=1.204*1023 molecules

Molar mass of ibuprofen is = 206g/mole 0.525 moles ibuprofen x (206g ibuprofen/1mole ibuprofen) = 108g ibuprofen

i would say no more than 3 at a time, maybe 15 per dayAT ABSOLUTE MAXor you could read the bottle where it tells you exactly what you should take...

if you use over 2,000 mg. it is very bad for you and you will probly end up throwing up all night. but it really deppends on how old you are and how much you way. normally if a kid is under 12 yr....

a Single dosage of no more than 2000mg is generally safe, however this depends on body weight, if you weigh 100 lbs don't have 2000mg.
