Answer:
Mass is the amount of matter in the object, and is not affected by gravity. Weight, on the other hand, is directly related to gravity and how much you pull to the ground.
Answer:
Partial pressure of Ne is 0.61 atm.
Explanation:
Mole fraction of a gas
in mixture = (no. of moles of the gas in mixture)/(total no. of moles of gases in mixture)
Here, total no. of moles of gases = (0.32 + 0.56) moles = 0.88 moles
So, mole fraction of Ne in mixture, 
Let's assume both He and Ne along with their mixture behaves ideally,
Hence, in accordance with Dalton's law of partial pressure-

Where,
and
are partial pressure of Ne and total pressure respectively.
So, 
So, partial pressure of Ne is 0.61 atm.
