The partial pressure of O2 in your lungs varies from 25 mm
Hg to 40 mm Hg. What mass of O2 can dissolve in 1.0L OF water at 25.0oC when
the O2 partial pressure is 40. mm Hg? Since the normal Water solubility of
oxygen at 25oC and pressure = 1 bar is at 40 mg/L water, the partial pressure
is only40 mmg Hg
Mass of 02 dissolve = (40 mmHg/760 mmHg)*( 40 mg/L) (1 L)
=2.10 mg O2 dissolved
<span>The answer is scientific law. This continuously relates in the same circumstances, and suggests that there is a fundamental association connecting its elements. Truthful and well-confirmed statements like "Mercury is liquid at STP" are measured too exact to be suitable as scientific laws. </span>
Answer:
45
Explanation:
There are 12 Carbons
There are 22 Hydrogens
There are 11 Oxygens.
I think the answer is either 0 or 45. But the wording is very sloppy. It is not really atoms that are present. There are ions.
Go with 45 but hold your nose when writing your answer.
