For test 6 (150 hevy 50 light particles), what is the pressure contribution from the heavy particles?
lawyer [7]

Answer:

The pressure contribution from the heavy particles is 17.5 atm

Explanation:

According to Dalton's law of partial pressures, if there is a mixture of gases which do not react chemically together, then the total pressure exerted by the mixture is the sum of the partial pressures of the individual gases that make up the mixture.

In the simulation:

the pressure of the 50 light particles alone was determined to be 5.9 atm, the pressure of the 150 heavy particles alone was measured to be 17.5 atm,

the total pressure of the mixture of 150 heavy and 50 light particles was measured to be 23.4 atm

Total pressure = partial pressure of Heavy particles + partial pressure of light particles

23.4 atm = partial pressure of Heavy particles + 5.9 atm

Partial pressure of Heavy particles = (23.4 - 5.9) atm

Partial pressure of Heavy particles = 17.5 atm

Therefore, the pressure contribution from the heavy particles is 17.5 atm

Retinol is 83.84% c, 10.58% h, and 5.58% o by mass. what is the molecular formula of retinol? add the missing subscripts.
ikadub [295]
Answer is: <span>molecular formula of retinol is C</span>₂₀H₃₀O.
n(C) = 83,84 g ÷ 12 g/mol.
n(C) = 6,99 mol.
n(H) = 10,58 ÷ 1,008 g/mol.
n(H) = 10,5 mol.
n(O) = 5,58 g ÷ 16 g/mol.
n(O) = 0,348 mol.
n(C) : n(H) : n(O) = 6,99 mol : 10,5 mol : 0,348 mol /:0,348.
n(C) : n(H) : n(O) = 20 mol : 30,1 mol : 1.
