Answer:
mass of the helium gas will be [tex]=8.1\times 10^{-7}kg[/tex]
Explanation:
We have given volume of the helium [tex]V=4.5m^3[/tex]
Density of helium gas [tex]d=1.8\times 10^{-4}cm^3=1.8\times 10^{-10}m^3[/tex]
We have find the mass of the helium gas
We know that mass is given by mass = volume×density
So mass = [tex]4.5\times 1.8\times 10^{-10}=8.1\times 10^{-10}gram=8.1\times 10^{-7}kg[/tex]
So mass of the helium gas will be [tex]=8.1\times 10^{-7}kg[/tex]
