    Answer:

    2220 Torr

    Explanation:

    Assuming constant temperature, we can solve this problem by using Boyle’s law, which states that:

    • V₁P₁=V₂P₂

    Where subscript 1 refers to the initial volume and pressure, while subscript 2 refers to the final state, meaning that in this case:

    • V₁ = 5.25 L
    • P₁ = 740 Torr
    • V₂ = 1.75 L
    • P₂ = ?

    We input the data:

    • 5.25 L * 740 Torr = 1.75 L * P₂
    • P₂ = 2220 Torr
