They can be classified as metals.
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
Answer:
K = 1.08 X 10¹²
Explanation:
The solved solution is in the attach document
Metallic bond is the electrostatic attraction between a positive ion and delocalised(free)electrons
Something that breaks with little force against it.
