To solve this problem we will apply Henry's law. This law states that at a constant temperature, the amount of gas dissolved in a liquid is directly proportional to the partial pressure exerted by that gas on the liquid. Mathematically it is formulated as follows:
Here
is the partial pressure of the gas.
is the concentration of the gas (solubility).
is Henry's constant, which depends on the nature of the gas, the temperature and the liquid.
At the same time we know the the concentration can be defined as the relation between the number of moles and volume, then
Then we have that the relation can be written now as,
Now the fraction of Oxygen in that quantity is 0.21, then
Mass of oxygen
Therefore the mass of oxygen is 30.1324mg
Joules is the unit so it would be 2090 joules or (J)
Answer:
A)
Explanation:
The lowest latitudes get the most energy from the sun. The highest latitudes get the least.
Force is (mass × acceleration) measured in Newton
Pressure is the 'force' per unit area measured in Newton/m^2 (pascal)
