How to calculate the number of moles from grams?
How to calculate moles from grams? – Grams to moles formula. To correctly estimate the number of moles, n, of a substance of a specific mass, m, (in grams), you need to follow the grams to moles formula: n = m / M,. where, M is the molar mass of this material. The unit is typically g/mol.; But wait, what actually is a mole?
How to convert ppm to mg / m3 for gases?
In the table below you can easily convert ppm to mg/m3 for diverse gases that may be measured using our air quality monitors. Formula: concentration (ppm) = 24.45 x concentration (mg/m 3) ÷ molecular weight. For example: 50 mg/m 3 of NH 3 (17.03 g/mol) 24.45 x 100 ppm / 17.03 = 71.785ppm.
How is the molar mass of a compound calculated?
The molar mass of a compound is given by the sum of the standard atomic weight (namely, the standard relative atomic mass) of the atoms which form the compound multiplied by the molar mass constant.
