The volume at 100 mmHg : 0.656 L

Further explanation

Boyle's Law  

At a constant temperature, the gas volume is inversely proportional to the pressure applied  

[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

V₁=3.5 L

P₁=2.5 kPa=18,7515 mmHg

P₂=100 mmHg

[tex]\tt \dfrac{18.7515}{100}=\dfrac{V_2}{3.5}\\\\V_2=\dfrac{18.7515\times 3.5}{100}=0.656~L[/tex]
