Question

The volume of helium in a blimp is 6.28 × 109 milliliters. The density of helium in the blimp is 0.1786 . Find the mass of the helium in the blimp. (Hint: 1,000 L = 1 cubic meter.)

A.
1,120 kg
B.
1.12 kg
C.
3.52 × 107 kg
D.
2,840 kg

Answer 1

The mass of the helium in the blimp is approximately 1.12 x 10^9 kg.

Step-by-step explanation:

To find the mass of the helium in the blimp, we can use the formula:

Mass = Density x Volume

Given that the density of helium is 0.1786 g/mL and the volume of helium in the blimp is 6.28 x 10^9 mL, we can calculate:

Mass = 0.1786 g/mL x 6.28 x 10^9 mL

Mass = (0.1786 g/mL) x (6.28 x 10^9) g

Mass = 1.12 x 10^9 g

Converting grams to kilograms, the mass of the helium in the blimp is 1.12 x 10^9 kg.
