Question

a sample of oxygen occupies 250 cm³ at 300k the volume occupied by it 35°c keeping pressure constant is ---------------​

Answer 1

Answer:

volume occupied by oxygen gas at 35°C is 256.6 cm³

Explanation:

Given

volume of oxygen gas  V₁ = 250 cm³

temperature T₁ =  300 K

temperature T₂ = 35°C ⇒ 35 + 273 ⇒ 308 K

volume of oxygen gas V₂ = ??

Pressure = constant

Solution

as we know that

V₁ / T₁ = V₂ / T₂.....................(i)

V₂ = 250 X 308 / 300

V₂ = 256.6 cm³

volume occupied by oxygen gas at 35°C is 256.6 cm³
