Answer:
0.222 moles of SO₂ are present inside the volcanic crater
Explanation:
We apply the Ideal Gases Law for this case, where the moles are the unknown:
P . V = n . R . T
We replace data from the problem but we first do some conversions:
200°C to K → 200°C + 273 = 473K
3500mL to L → 3500mL . 1L / 1000 mL = 3.5L
250 kPa to atm → 250 kPa . 1 atm / 101.3 kPa = 2.46 atm
3.5L . 2.46 atm = n . 0.082 . 473K
(3.5L . 2.46 atm) / (0.082 . 473K) = n → 0.222
