Explanation:
Answer:
5.72 grams of O₂ are present in the sample
Explanation:
Let's calculate the moles of O₂ by the Ideal Gases Law.
P . V = n . R . T
1.66 atm . 2.50L = n . 0.082 . 283K
(1.66 atm . 2.50L) / 0.082 . 283K = n
0.179 mol = n
Molar mass O₂ = 32 g/m
Mol . molar mass = mass → 0.179 m . 32g/m = 5.72 g
