9 electrons :) I can't give a sbs explanation but here we go
Explanation:
It is known that for
, ppm present in 1
are as follows.
1
= 0.494 ppm
So, 150
= 
= 0.15 
Therefore, calculate the equivalent concentration in ppm as follows.

= 0.074 ppm
Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
The boiling point (or condensation point) of a substance is defined as the temperature at which the vapor pressure of the liquid is exactly equal to the external pressure. Above the boiling point, the substance exists as a gas and below, it exists predominately as a liquid.
Answer:
The definition of air pressure is the force exerted onto a surface by the weight of the air. An example of air pressure is the average sea-level air pressure of 101.325
Explanation:
C. Increases. Increasing temperature=Increasing Volume
