Answer
25.1 g
Work Step by Step
We compute the molar mass using the number of each type of atom present and the molar mass of each element present:
$8(12.01 g/mol) + 9(1.01 g/mol) + 2(16.01 g/mol) + 1(14.01g/mol)$
This gives:
151.16 g/mol
We now find the number of grams present in the sample:
$$\frac{.166 \ mol}{1} \frac{151.16 g}{mol}= 25.1\ g$$
