8. Convert 0.0035% NaCl by mass into parts per million of NaCl. 0.0035% by mass means 0.0035 g of NaCl per 100 g of solution • You can also just prove this to yourself another way. Assume you have 100 g of solution (or any other mass for that matter) and use %bymass= massof solute massof solution to figure out the mass of solute ppm= massof

Assuming you are converting the mass of a substance, the conversion of mg/kg to ppm is 1:1. To convert to parts per million, you don't need to do anything other

Parts-Per-Million By Mass In liquids, it is common to use ppm by mass as a concentration. In general the calculations are a lot easier than in the gas phase. 1 ppm solute = 10-6 kg solute / 1 kg solution = 1 mg solute / 1 kg solution There is a very convenient way to do this calculation in dilute solutions of water.

The abundance of elements in Earth's crust is shown in tabulated form with the estimated crustal abundance for each chemical element shown as mg/kg, or parts per million (ppm) by mass (10,000 ppm = 1%).

Luftflödet reglerades/späddes med en kalibrerad massflödesregulator (Bronkhorst Low ΔP Flow). Den lägsta koncentration som kunde genereras var 4000 ppm 

If the solvent is water, we can assume the density at standard temperature and pressure is 1.0 g/mL. The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Since 1 liter of water has a mass of 1 kg, any concentration expressed in mg/L is already in PPM because it’s equivalent to mg/kg.
