A weather balloon holds 2,600 cubic meters of helium. the density of helium is 0.1755 kilograms per cubic meter. how many kilograms of helium does the balloon contain? please round your answer to the nearest whole number. only enter a numerical value in the answer blank.


  1. Answer:
      456 kg
    Step-by-step explanation:
    Mass is the product of volume and density.

    Mass of He

    The product of volume and density is …
      M = Vρ
      M = (2600 m³)(0.1755 kg/m³) ≈ 456 kg
    The balloon contains about 456 kg of He.
