The equivalent unit was introduced to account for the fact that when solutes dissolve in solvent to create a solution, the number of particles dispersed depends on the valence of the solute. For example, when one molecule of KCl dissolves, it leaves two ions, or charged particles − a K+...
Step 1 Determine the moles of chemical contained in 1 liter (L) of the solution. Since molarity is the moles chemical per liter, this value will simply equal the molarity of the solution. For example, if you have a solution of potassium chloride (KCl) in water which is 2.50 molar, ...
Molar Mass of HCl: 36.46 g/mol ElementSymbolAtomsMass % Hydrogen H 1 2.8% Chlorine Cl 1 97.2% Here, the focus will be specifically on how to make solutions with their concentrations expressed as weight by volume or w/v.Why Use W/V? Why are there so many different ways to express ...

How much solid agarose and how much water would you use to make 100 ml of a 1.5 % agarose solution? After 1.00 mL of water is completely vaporized to gas, how many milliliters of vapor are produced at standard temperature and pressure? (Density of water is 1.00 g/mL; the molar volume...
The mass of one mole of an element or a compound is equal to the mass number of the molecule expressed in the units of a gram. We can find the moola mass of a compound or an element from the molecular formula. To find the molar mass, we have to add the molar mass of each atom...
These rate differences are such that the addition of a small excess of enzyme will avoid any problems due to incomplete digestion. As always, however, one must be aware of the experimental molar concentration of recognition sites and digest conditions relative to that of the unit definition. See...
