The Equation of State (EoS) by Span and Wagner (1996) is used to calculate the properties of pure CO 2 at the temperatures from -56.558-826 o C and pressures up to 8000 bar Lower limit for calculation: -210 C, 0.13 bar bar upper limit: -148 C, 33 bar. Ideal gas equation is, PV = nRT. This online unit converter will help you to convert the number moles to the number of grams of the atom based on the weight of the given chemical equation / formula. Molar concentration, also known as molarity, and can be denoted by the unit M, molar. To prepare 1 L of 0.5 M sodium chloride solution, then, as per the formula, use 29.22 g of sodium chloride (0.5 mol/L * 1L * 58.44 g/mol = 29.22 g).

In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. Many of these use mass rather than number of moles, or they arrange them as different ratios. This is also referred to as molarity, which is the most common method of expressing the concentration of a solute in a solution.Molarity is defined as the number of moles of solute dissolved per liter of solution (mol/L = M).
