Question

The nonprescription pain relievers Advil and Nuprin contain ibuprofen (C13H18O2), whose molecular mass is 206.3 amu. If all tablets in a bottle of a pain reliever together contain 0.082 mol of ibuprofen, what is the number of grams of ibuprofen in the bottle?

Answer 1

Answer:

16.92 g C13H18O2

Explanation:

If the molecular mass of C13H18O2 is 206.3 amu, then molar mass of C13H18O2 is 206. 3 g/mol.

So, if we have 0.082 mol C13H18O2, than it is

206.3 g/mol*0.082 mol = 16.92 g C13H18O2.
