Answer
There are 108 g of ibuprofen in 0.525 mole of that.
Work Step by Step
As we have calculated in 7.74a, the molar mass of ibuprofen is equal to:
206.2 g/mole
Therefore, the conversion factors are:
$ \frac{1 \space mole \space (C_{13}H_{18}O_2)}{ 206.2 \space g \space (C_{13}H_{18}O_2)}$ and $ \frac{ 206.2 \space g \space (C_{13}H_{18}O_2)}{1 \space mole \space (C_{13}H_{18}O_2)}$
2. Calculate the mass:
$ 0.525 \space mole \times \frac{ 206.2 \space g}{1 \space mole} = 108 \space g$
