Selenocysteine is an amino acid that gets incorporated into proteins that serve as antioxidants.Evidence points to a need for a minimum daily dose of selenium of 55 $\mu$g.How many moles of selenocysteine (C₃H₇NO₂Se, 168.00 g /mol) can be synthesized using this amount of selenium?

Given the minimum daily dose of selenium is 55 µg and the molar mass of selenocysteine is 168.00 g/mol, we can calculate the moles of selenocysteine that can be synthesized as follows:First, convert the amount of selenium from micrograms (µg) to grams (g) to match the units of the molar mass:$$55 \mu g = 55 \times 10^{-6} g$$Then, use the molar mass of selenocysteine to find the moles of selenocysteine that can be synthesized from this amount of selenium:$$\frac{55 \times 10^{-6} g}{168.00 g/mol} = 3.273 \times 10^{-7} mol$$This value is closest to the option:$$3.3 \times 10^{-7} mol$$
