Mass is always constant for a body. One way to calculate mass:Mass = volume × density. Weight is the measure of the gravitational force acting on a mass. How To Calculate The Molar Mass of a Compound - Quick & Easy! 27 related questions found How do you calculate molecular mass and f...
How many moles of H2SO4 would be required to react completely with 0.413 moles Al? Al(s) + H2SO4(aq) to Al2(SO4)3(aq) + H2(g) How many moles of Al(OH) are required to completely react with 2.75 mol of H2SO4? For the given re...
This leads to the definition of an equivalent, or specifically a milliequivalent: (mEq = dfrac{(mass)(valence)}{MW}) This equation assumes that both mass and MW, or molecular weight (the same as molar mass but applied to molecules instead of single atoms), are given in milligrams. ...

take 0.05 ml = 50 ul of stock solution and dilute it with 150 ul of solvent to get the 200 ul of 25 mg/ ml solution needed (remember that the amount of solvent used is based upon the final volume needed, so you have to subtract the starting volume form the final to calculate it....
Either a mass basis or the surface area of the component being extracted can be used to determine the amount of extraction solvent utilized. As a rule, the surface area approach is favored and a surface area of volume ratio of 3 cm2/ml is applied for majority of samples. Higher volumes ...
The chemical formula is the formula of a compound in which: We can see which atoms for a certain molecule. Also, we can determine the number of each atom. Most interesting, by adding up the mass of each atom we can get the mass of the molecule....
