Question

100 PNTS PLZ ANSWER ASAP PLZ The masses of a sample of hydrogen gas and a sample of helium gas are the same: 1 g. The density of hydrogen is 0.00009 g/cm3 and the density of helium is 0.00018 g/cm3. Which is an accurate description of their relative volumes? A. The volumes of the hydrogen and helium samples are the same. B. The volume of the hydrogen sample is greater than the volume of the helium sample. C. The volume of the hydrogen sample is smaller than the volume of the helium sample.

Answer 1

i think the answer is b.

Step-by-step explanation:

i took the test and got this right. Its the volume of the hydrogen sample is greater than the volume of the helium sample.

Answer 2

the volume of the hydrogen sample is greater than the volume of the helium sample.

Step-by-step explanation:

Density=mass/volume

Now just plug each value in the given equation

For Helium

0.00018 g/cm3 = 1g/x

x= 5555.56 cm3

For hydrogen

0.00009gcm3=1g/x

x= 11111.11 cm3

This shows us that the volume of the hydrogen sample is greater than the volume of the helium sample.

I think this is correct but double check my work and ask others as well!
