Answer:
31.6 L would be equal to 13.5 MARIA. 31.6 L would be equal to 13.5 MARIA
Explanation:
<span>We're diluting the first solution to make the second solution. This means both solutions will contain the same amount of H2SO4 (it's the concentration of it that changes). If you look at it this way, it's easy to find the unknown mass. Call this unknown mass m.
m * 0.875 = 275 g * 0.55 --> m = 173 g
What I'm saying here is 87.5% of the mass of the first solution needs to be the same as 55% of the mass of the second solution, because you're using the same amount of H2SO4 in both.

Answer:
Xe will have the highest partial pressure
Explanation:
Using Dalton's law of partial pressures for ideal gases
p=P*x
where
p= partial pressure , P= total pressure and x = mole fraction = n / ∑n
since the number of moles is related with mass through
n= m/M
where
m= mass and M= molecular weight
then if m is the same for all the gases
x = m*M/ ∑ (m*M) = m*M/ m∑ M = M/∑ M
thus
p=P*x = P*M/ ∑ M
for the 3 gases
p₁=P*x₁ = P*M₁/ (M₁+M₂+M₃)
p₂=P*x₃ = P*M₂/ (M₁+M₂+M₃)
p₂=P*x₃ = P*M₃/ (M₁+M₂+M₃)
then for gasses under the same pressure (P=constant) and same mass (m=constant) , p is higher when the molecular weight is higher . Therefore Xe will have the highest partial pressure
