Weight percent is essentially the same as (I arbitrarily picked grams as the mass unit): % w / w X = g X g s o l u t i o n. In order to get to the m o l L units of molarity, you have to convert by multiplying by the solution density, ρ, and dividing by the molecular weight of X, M X: g X g s o l u t i o n × m o l X g X ( 1 M X) × g s o l ...
Normality - Formula, Definition, Examples, Problems
WebThe atomic mass of all atoms can be found in the periodic table. For dilute solutions, one part per million equals one mg/L. In most cases, the two are considered equal. To convert from molarity to ppm, first determine the molar mass of a substance. For instance, chloride has a molar mass of 35.5. A solution with 1 M concentration would have 35 ...
