Question

The density of hydrogen is approximately 9 × 10^5 g/cm^3, while the density of helium is approximately 2 × 10^4 g/cm^3. Which of the following is true?
A. The density of hydrogen is approximately 2 times the density of helium.

B. The density of hydrogen is approximately 20 times the density of helium.

C. The density of helium is approximately 20 times the density of hydrogen.

D. The density of helium is approximately 2 times the density of hydrogen.

Answer 1

C. The density of helium is approximately 20 times the density of hydrogen.

Answer 2

are you sure

Answer 3

Apologies for the confusion in my previous response. Let's reassess the densities of hydrogen and helium.

Density of hydrogen = 9 × 10^5 g/cm^3
Density of helium = 2 × 10^4 g/cm^3

To determine which statement is true, we can calculate the ratio of the density of hydrogen to the density of helium:

(9 × 10^5) / (2 × 10^4) = 45

Since the ratio is 45, it means that the density of hydrogen is approximately 45 times the density of helium. Therefore, the correct option is:

B. The density of hydrogen is approximately 45 times the density of helium.
