Ibuprofen is an anti-inflammatory with the formula C13H18O2. How many grams of ibuprofen are in 0.495 mol? How many moles of carbon are in 10.0 g of ibuprofen? How many moles of ibuprofen contain 1.15×1023 atoms of carbon?
mass of ibuprofen = mole * molar mass of ibuprofen
molar mass of ibuprofen = 206.3 grams/mole
= 0.495 * 206.3
= 102.1185 grams
moles of ibuprofen in 10 grams = mass / molar mass
= 10.0 / 206.3
= 0.0485
formula of ibuprofen = C13H18O2
1 mole have 13 carbon
0.0485 mole will have = 13 * 0.0485
= 0.6305 moles of carbon
Now for third part
moles of carbon = number of carbon atoms / avagadro number
= 1.15*10^23 / (6.022*10^23)
= 0.191
moles of ibuprofen = 1/13 * moles of C
1/13 * 0.191
= 0.0147 moles
