Answer:

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

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!
