Question

Please solve numericals 4,5,6 on the basis of gas laws

Answer 1

Answer:

4) 1090 mm Hg

5) 10000 flasks

6) 464 Litre

Explanation:

4. Gas remaining = (100 - 40) % = 60 % = 0.6 = $\frac{V_2}{V_1}$

P₁V₁ = P₂V₂

►P₂ = $\frac{P_1V_1}{V_2}$ =  654 / 0.6 mm Hg = 1090 mm Hg

5. P₁V₁ = P₂V₂

► 100 × 20 = 1 × V₂

► V₂ = 2000 Litre = 2000000 cm³

No. of flask = 2000000/200 = 10000

6, P₁V₁ = P₂V₂

► 29 × 20 = 1.25 × V₂

► V₂ = 580/1.25 = 464 Litre
