Answer:
Partial pressure of hydrogen H₂ = 0.32 atm
Explanation:
Given:
Total pressure = 0.48 atm
Find:
Partial pressure of hydrogen
Computation:
Number of mole of H₂ = 1 / 2 = 0.5 moles
Number of mole of He = 1 / 4 = 0.25 moles
Total moles = 0.5 + 0.25 = 0.75
Partial pressure of hydrogen H₂ = [moles / total moles] Total pressure
Partial pressure of hydrogen H₂ = [0.50 / 0.75]0.48 atm
Partial pressure of hydrogen H₂ = 0.32 atm
Whats the options? I need to see some options before I answer please if there are any..
False. The principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
<h3>What is Archimedes' principle?</h3>
It is a theory propounded by Archimedes. It opines that a floating body is acted upon by a buoyant force.
The buoyant force is the same as the weight of the fluid displaced by the floating body.
Thus, instead of saying 'the buoyant force is equal to the blank of the fluid displaced', it is actually 'the buoyant force is equal to the weight of the fluid displaced'.

Answer: because the particles in a solid are more closer to each other than the liquid and gas particles. So the closeness if the particles give a particular shape for the substance.
Please add me to the brainleist please!!!!!!!!
