There are many different ways of expressing the concentration of a given solution. Some of the most common include molarity, weight by volume, volume by volume and weight by weight. Weight by volume percent (w/v %) tells you the mass of solute in grams t
Conversion of weight percent to molarity *Cw=(10×Mw×M)/ρ Where Cw is weight percent Mw is molar mass M is molarityρ is density of the solution Assumption: -No reaction between ammonium hydroxide and hydrogen peroxide -Hydrogen peroxide Density = 1.44g/mL Cw = 31wt% Mw = 34g/mol...
the total mass of one mole of butane =58.123 mass of hydrogen in one mole of butane = 10.0794 therefore, the mass percent of hydrogen in butane \(\begin{array}{l}= \frac{10.079}{58.123}×100\end{array} \) = 17.3 % these concepts play a very important role in studying the ...
the distinction becomes significant for measurements with an accuracy better than a few percent, and for locations far from the surface of the earth, for instance in space or on other planets. weight and mass are related by the equation, w = m g wherein w is the weight, m is the mass...
