Answer:
Ppm <u>means the concentration of vapors or gases</u> expressed in parts per million of polluted air.
Explanation:
In Chemistry and Physics, part per million or PPM is a measure that expresses the number of units of a certain existing substance for every million units of the mixture. (Concentration)
In climate the equation is used so:
- ppm = parts of polluted air / million parts of air
.
- ppm = Liters of polluted air / 10∧6 Liters of air.
This is used to find the concentration of gases expressed as parts of gas per million parts of the
polluted air.
In this case, it would be<u> 407.4L of CO2 per 10∧6L of air.</u>
Stored mechanical energy is energy stored and awaiting to be used and mechanical energy is the energy that was stored being used.
Answer:
Explanation:
AgCl ⇄ Ag⁺ + Cl⁻
m m m
If x mole of AgCl be dissolved in one litre .
[ Ag⁺ ] [ Cl⁻ ] = 1.6 x 10⁻¹⁰
m² = 1.6 x 10⁻¹⁰
m = 1.26 x 10⁻⁵ moles
So solubility of AgCl is 1.26 x 10⁻⁵ moles / L
