A given mass of a gas occupies volume of 2.5dm³ at NTP. calculate the change in volume of gas at the same temperature if pressure of a gas is changed to 1.04*10⁵Nm^-2

Initial volume, V₁ = 2.5 dm³
Initial pressure, P₁ = 1.01 $\times$ 10⁵ Nm^-2
Final pressure, P₂ = 1.04 $\times$ 10⁵ Nm^-2
​Final volume = V₂
Temperature remain same, using Boyle's law equation:
P₁V₁ = P₂V₂
1.01 $\times$ 10⁵ Nm^-2 $\times$ 2.5 dm^3​ = 1.04 $\times$ 10⁵ Nm^-2 $\times$ V₂
​V₂ = 2.43 dm³

Change in volume = V₁ - V₂ =  0.07 dm³
