<u>Answer:</u> The partial pressure of oxygen gas is 57.8 kPa
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of oxygen gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the tank, = 201.4 kPa
Vapor pressure of helium, = 125.4 kPa
Vapor pressure of carbon dioxide, = 18.2 kPa
Putting values in above equation, we get:
Hence, the partial pressure of oxygen gas is 57.8 kPa
The number of neutrons is different in each isotope of an element.
A scientist would measure the amount of carbon-14 (¹⁴C) in a fossil to determine its age.
The ¹⁴C:¹²C ratio is constant in living organisms. When they die, the radioactive ¹⁴C decays, so the ratio changes. The half-life for the for the decay is 5730 a, so scientists can work backwards and calculate how long ago the plant died. The method is good for determining the age of fossils up to 50 000 a old.
