5. A particular vitamin's chemical formula has one cobalt atom. (3 points) a) What is the molar mass of the vitamin if it contains \( 4.34 \% \) cobalt? \[ 434 \% \times 58.933200=\sqrt{253} \times 1 \mathrm{~mol} \] \[ -0 . S \] \( \frac{58.93}{4.43 \times 100}=1358 \rightarrow 13609 \) b) How many milligrams of the vitamin would give you \( 5.00 \mathrm{mg} \) of cobalt? \( \frac{253.9}{1} \times \frac{1}{10^{-3} \mathrm{~g}} \times \frac{1}{5.00 \mathrm{mg}}=50600 \mathrm{mg} \)
