# 1) Unless specified otherwise, ppm usually refers to ppm by weight: 2.89 ppm = 2.89 g per 1,000,000 g (or any other weight unit, I have just chosen g for convenience) 2) Now you need to know the density of the solvent to convert the volume to mass. If the solvent is water, we can assume the density at standard temperature and pressure is 1.0 g/mL.

ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000. ppm is dimensionless quantity, a ratio of 2 quantities of the same unit. For example: mg/kg. One ppm is equal to 1/1000000 of the whole: 1ppm = 1/1000000 = 0.000001 = 1×10-6 . One ppm is equal to 0.0001%: 1ppm = 0.0001%. ppmw

given: Specifications, →98% pure solution →Density = 1.84 gm/ml →Molecular Weight =… The ppm measure simply says how many µg/g (weight) or molecules per million molecules (molar ratio) of NH3 there are in the mix. Assuming that your 1:10 mix is calculated in weight, the This converter converts parts per million (ppm) to weight percent (%) online. The parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement.
