The molecular weight of glucose is approximately 180 daltons so each mol of glucose will be equal to 180g glucose. The concentration of glucose in the blood would be: 100mg/dl * 1 mol/180g= 5.55 mol/dl * 10^-4
Molar is expressed as mol per liter, so you need to change the volume into liters. The calculation would be: 5.55 mol/dl * 10^-4 * 10dl/liter= 5.55 * 10^-3 M= 5.55 millimoles
The molarity of this solution in millimoles is 5.6.
The mole is the unit of measurement in the International System of Units (SI) for amount of substance. It is defined as the amount of a chemical substance that contains as many elementary entities, e.g., atoms, molecules, ions, electrons, or photons, as there are atoms in 12 grams of carbon-12 (C), the isotope of carbon with relative atomic mass 12 by definition.
