Answer:
0.85 atm
Explanation:
We start by getting the total number of moles of all gases.
Total moles = 0.220 + 0.350 + 0.640 = 1.21 mol
Then we get the fraction of Oxygen moles and multiply by the total pressure;
The pressure of O2 = 0.350 mol / 1.21 mol x 2.95 atm
= 0.85 atm
Answer:moon phases
Explanation:
Moon phases because the moon phases changers every day
Answer: 40 + 2x14 + 6x16 = 164g/mole
54.3g x [1mole / 164g] = 0.331moles
355mL x 1L / 1000mL = 0.355L
molarity = 0.331moles / 0.355L =
00
Explanation:
P₁ = 0.90 atm
V₁ = 50.0 mL
T₁ = 298 K
P₂ = 1 atm
T₂ = 273 K
V₂ = P₁ x V₁ x T₂ / T₁ x P₂
V₂ = 0.90 x 50.0 x 273 / 298 x 1
V₂ = 12285 / 298
V₂ = 41 mL
