The Spirit of America Goodyear blimp has a volume of 2.027*105 ft3. When the blimp is in operation, it is filled with helium gas. If the density of helium at room temperature is 0.179 g/L, calculate the mass of helium in the blimp.

Answer: 1.027 x 10^6 g = 1027kg

In this question, you are given the volume of the blimp (2.027*10^5 ft^3) and the density of the gas (0.179g/L). To answer this question, you need to convert the volume unit into liter. The calculation would be: 2.027*10^5 ft^3 x 28.3168L/ft3 = 57.398 x 10^5L = 5.74x10^6L

Then to find the mass, multiply the volume with the density. The calculation would be: 5.74x10^6L x 0.179g/L = 1.027 x 10^6 g = 1027kg
