8. A party-supply store sells a helium-gas

cylinder with a volume of 1.55 x 10-2 m². If

the cylinder provides 1.81 m3 of helium for

balloon inflation (at 0 °C and 1 atmosphere),

what must be the pressure inside the

cylinder? eldsinsvinebnegabais

P₂ = 116.7 atm

Explanation:

Here apply the Boyle's law equations that states : at constant temperature the volume of a dry mass of a gas is inversely proportional to its pressure.

This is simplified as;

P₁V₁=P₂V₂ where P is pressure and V is volume

Given that;

P₁=1

V₁=1.81 m³

P₂=?

V₂=1.55*10^-2 m³

Apply the formula

1*1.81 = P₂*1.55*10^-2 m³

1.81/1.55*10^-2 = P₂

P₂ = 116.7 atm
