Question

Th volume of helium in a blimp is 6.28x10^9 millimeters. Thr density of helium is a blimp is 0.1786 meters. Find the massof the helijm blimp

Answer 1

The mass of the blimp is 1.12 kg.

Step 1. Calculate the volume of the blimp.

V = 6.28 × 10⁹ mm³ × (1 m/1000 mm)³ = 6.28 m³

Step 2. Calculate the mass of the helium.

Mass = 6.28 m³ × (0.1786 kg/1 m³) = 1.12 kg

Answer 2

Answer: The mass of the helium blimp is 1.126 kg.

Explanation:

Density is defined as the ratio of mass and volume.

Mathematically,

$Density=\frac{Mass}{Volume}$

We are given:

Density of the helium blimp = $0.1786kg/m^3$

Volume of the helium blimp = $6.28\times 10^9mm^3=6.28m^3$    (Conversion factor: $1mm^3=10^{-9}m^3$ )

Mass of the helium blimp = ? kg

Putting values in above equation, we get:

$0.1786kg/m^3=\frac{Mass}{6.28m^3}\\\\Mass=1.126kg$

Hence, the mass of the helium blimp will be 1.126 kg.
