Answer 1

Answer #1

Part A

after addition of 0.117 mole of gas final mole = 0.119 + 0.117 = 0.236 mole

we know avogadro's law volume of gas directly proportional to no. of mole of gas at constant tempreture and pressure.

V $\alpha$ n

another form of this equation

V₁/n₁ = V₂/n₂

where V₁ = initial volume = 2.83 L

V₂ = final volume = ?

n₁ = initial mole = 0.119 mole

n₂ = final mole = 0.236 mole

We can wright above eqation as

V₂ = V₁n₂/n₁

Substitute value

V₂ = 2.83 X 0.236 / 0.119 = 5.61 L

final volume of gas = 5.61 L
