Answer:

972 ppm

Explanation:

Percent (parts per hundred - pph), parts per million & parts per billion are ratios of a component of interest divided by total mix of several components.

That is, given 28%, this says 28/100, or 28ppm says 28/10⁶, or 28ppb says 28/10⁹.

To convert from the given (=> any of the three concentration ratios) simply multiply (X) where you wish to go.

Examples:

  • Convert 35% to ppm and ppb
  • 35% = (35/100) x 10⁶ppm = 3.5 x 10⁵ ppm
  • _______________________________
  • Convert 43 ppm to %
  • 43 ppm = (43/10⁶) x 100% = 4.3 x 10³%
  • ______________________________
  • Convert 81 ppb to ppm
  • 81 ppb = (81/10⁹) x 10⁶ppm = 8.1 x 10⁻² ppm

Notice how each 'Given' is expressed as a ratio of amount/100 (given pph or %),  or amount/10⁶ (given ppm) or amount/10⁹ (given ppb). All you need to do here is multiply by where you want to go.

=> Given % = (amount/100) x 10⁶ => ppm

=> Given ppm = (amount/10⁶) x 100 => %, or pph

=> Given ppb = (amount/10⁹) x 10⁶ => ppm

Given ratio x 100 = %, or x 10⁶ => ppm or x 10⁹ => ppb

Your Problem:

Given = (0.0972g/100g) x 10⁶ppm = 972 ppm

or, if you wish ppb => (0.0972g/100g) x 10⁹ppb = 972,000 ppb
