Question

the volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

Answer 1

Answer : The mass of the helium in the blimp is, 1.1216 Kg

Solution : Given,

Volume of helium in the blimp =
`6.28* 10^(9)mm^3=6.28m^3`

conversion :
`1mm^3=10^(-9)m^3`

Density of helium in the blimp =
`0.1786Kg/m^3`

Formula used :

`Density=(Mass)/(Volume)`

Now put all the given values in this formula, we get the mass of helium in the blimp.

`0.1786Kg/m^3=(Mass)/(6.28m^3)`

`Mass=1.1216Kg`

Therefore, the mass of the helium in the blimp is, 1.1216 Kg
