Consider a childrens cartoon illustrating a child holding the strings of several helium balloons and being lifted

Question:

Consider a children’s cartoon illustrating a child holding the strings of several helium balloons and being lifted into the sky.

a. Estimate the minimum number of 10-L balloons it would take to lift a 50-lb child. Assume air has an average molar mass of 29 g/ mol, and assume the masses of the balloons and strings are negligible.

b. Explain why the balloons can lift the child.
