The molar mass of PCP (phencyclidine) is 243.387 grams per mole. So 1000 g of PCP is equal to 4.108 moles. If that many moles is in 1000 liters, than the molarity (in moles per liter) is 4.108 ÷ 1000 = 0.0041 M
This is a molar concentration.
That would be one way of doing it. Chemists normally measure concentration of a solute in terms of moles per liter.
The molarity of a solution is the number of moles of a solute per liter of its solution. The normality of a solution is the number of gram equivalent weight of a solute per liter of its solution. As I said before, and precisely, Molarity is moles of solute per VOLUME of solution!
A known quantity of a substance is dissolved in solution for a standard solution. This is expressed as units of mole per liter, moles per cubic centimeter, or in terms of that particular titration.
moles per liter.
This kind of concentration is known as The units are m (not capitalized) Do not confuse this with molarity (M) which is moles of solute per Liter of solution.
Relative concentration gives you a comparison of two or more solutions, telling you which has a higher concentration of some solute than the other. Precise concentration would normally be expressed in terms of moles per liter, and it tells you the actual amount of a solute that is present in a given volume of solution.
Mass of solute X 100 Mass of solvent
This is known as the concentration or more technically the molarity or molality of the solution.
salinity
A concentration scale that gives the number of formula weights of solute per liter of solution
a PH probe measures the concentration of Hydrogen ions in a solution in moles per litre. In less scientific terms it measures how acidic or basic a solution is.
