Atoms, molecules and stoichiometry — practice question

In China, blood glucose concentration, $C_6H_{12}O_6$, is reported in $\text{mmol l}^{-1}$. In Pakistan, blood glucose concentration is reported in $\text{mg dl}^{-1}$. The unit $l$ means a litre ($1\,\text{dm}^3$). The unit $dl$ means a decilitre ($0.1\,\text{dm}^3$). A blood glucose concentration of $18.5\,\text{mmol l}^{-1}$ shows that there is a health problem. What is $18.5\,\text{mmol l}^{-1}$ expressed as $\text{mg dl}^{-1}$?

  • A$33.3\,\text{mg dl}^{-1}$
  • B$178\,\text{mg dl}^{-1}$
  • C$333\,\text{mg dl}^{-1}$
  • D$3330\,\text{mg dl}^{-1}$
