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:
<h2>15 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>15 m/s²</h3>
Hope this helps you
Isotopes of an element have same atomic number (number of protons) but vary in the mass number (number of neutrons). The chemical reactivity of an element is not affected by the change in mass number. So, for stable isotopes of Oxygen, (Oxygen-16, Oxygen-17 and Oxygen-18) the biochemical pathway of oxygen breathed in during respiration remains unaffected even with different isotopes. Only the radioactive isotopes of oxygen when breathed in may cause serious health hazards as they emit radiations that may damage the internal organs in the body.

Thomson's model of the atom was called the plum pudding model. He discovered electrons, so he placed them in the atoms. This was before the nucleus was discovered.
Now, the current model is an atom that contains a positively charged nucleus (with both protons and neutrons), and negatively charged orbitals with electrons.
