Answer:

The answer 772.5

Step-by-step explanation:

You would use the density formula to figure out the mass.

Density = mass/volume

We have the density of helium (0.1785) and the volume of how much the hot air balloon can hold (4,328).

0.1785 = x / 4,318

0.1785 * 4,318 = x

772.548 = x

Then rounded to the nearest tenth would be 772.5, the third option.
