Calculate the number of millimoles (mmol) of citric acid found in 1.00 g of citric acid. (1 mmol = {eq}1 \times 10^{-3} {/eq} mol) Molar Mass: The molar mass is a quantity of substances that defines the mass per mole. This is the key quantit...
Several formulae for the estimation of body surface area (BSA) are used in the medical literature to index a number of biological variables including left ventricular mass (LVM). Most authors estimate BSA using the 1916 Dubois formula {(Weight, kg) * (Height, cm)* 0.007184} which was ...
The number of water molecules present in every formula unit of the ionic compound determines the water of crystallization or water of hydration of the salt. The value of the water of crystallization varies from one salt to another...
