Question

(b)

The helium in the balloon has a mass of 0.00254 kg.
The balloon have a volume of 0.0142m^3 calculate the density of helium

Answer 1

0.17887 kgm⁻³

Step-by-step explanation:

We know,

p = m/V

Here,

p = density

m=mass =0.00254 kg.

v = volume =0.0142m³

Now,

p = 0.00254 kg/0.0142m³

=

∴The density of helium 0.17887 kgm⁻³
