So we need to convert the concentration to moles per liter, multiply by the volume to get total moles and convert moles to grams of fluoride. a) 1.6 ppm is 1.6 x 10-6 g/g of solution or 1.6 mg / kg of solution.

Calculate the ppm of $\ce{Fe^2+(aq)}$ if $\pu{0.0055 g}$ of $\ce{Fe(NO3)2}$ is dissolved in $\pu{2.0 kg}$ of water. I have tried converting g of iron nitrate into moles, using mole ratio between iron nitrate and iron(II) ions and then converting to grams of iron(II) ions.

α-Fe2O3 nanochains have been successfully synthesized via an ammonium acetate-based ionothermal synthetic route. When detecting low-ppm-level H2S gas, the nanochain sensor displayes high sensitivity due to its unique structure and smaller size.

Converter Parts Per Million (ppm) Parts Per Million (ppm) Converter for Gases. This converter calculates the measured value in units of [ppm] into units of [mg/m 3] and visa versa. The unit ppm is used in several branches in different ways. The use of ppm therefore has to be specified in the input fields below, in the way it should convert the ...

Find the conversion for CaCO 3 to CaO and use the multiplying factor beside CaCO 3. The result is 56 x 1.7848 = 99.94% CaCO 3 . A factor is the sum of the atomic weights of the elements in the required formula divided by the sum of the atomic weights in the original formula.
