The molecular formula of OF2 is given, where the molar mass of OF2 can be calculated as follows: O (16 g/mol) + 2*F (2*19 g/mol) = 16 + 38 = 54 g/mol. Therefore, 27 g of OF2 is 27 g / 54 g/mol = 0.5 moles. Since each molecule of OF2 contains one atom of oxygen, there are also 0.5 moles of O atoms in 27 g of OF2.
