Answer:
1.8x10¹⁷ molecules of CO are in each breath we take
Explanation:
Parts per million, ppm, is an unit of concentration in chemistry used for very diluted solutions.
<em>A 9ppm of X in a solution means in 1 million of molecules (1x10⁶) you have only 9 molecules of X.</em>
In a breath we have 2x10²² molecules and 9 ppm are CO. Thus, CO molecules in each breath are:
2x10²² molecules × (9 molecules CO / 1x10⁶ molecules) =
<h3>1.8x10¹⁷ molecules of CO are in each breath we take</h3>
To find the atomic mass of chlorine, the atomic mass of each isotope is multiplied by the relative abundance (the percent abundance in decimal form) and then the individual masses are added together. The atomic mass of chlorine is 35.45 amu.

Hydrogen Bond is the bond based on intermolecular forces between H and F O and N
Answer:
The plants in the northern and southern states during the summer receive the most sunlight and experience a growth period.
Explanation:
The plants in the northern and southern states during the summer receive the most sunlight and experience a growth period because in the summer season, plants receive more solar radiation as compared to winter season. Plant needs more solar radiation for higher growth. Photosynthesis is the process which helps the plant to produce more vegetation and this will only happens when the sunlight is high so we can say that summer season enables the plant to have more vegetative growth.
