Determine the density of a gas weighing 20kg, filling a goldfinch ball with a volume of 10m3.

Let’s write down briefly given:

m = 20 kg;

V = 10 m ^ 3.

To find:

p (gas density) -?

Let’s first of all remember what the density of a gas is and the formula for finding it.

The density of gases is the mass of a substance per unit volume – g / cm ^ 3.

The absolute density of a gas is the mass of 1 liter of gas under normal conditions. It is usually measured in g / l for gases.

To calculate it, use the formula:

p = m / V.

We substitute the values into the formula and perform the calculations:

p = 20 kg / 10 m ^ 3 = 2 kg / m ^ 3 = 0.002 g / cm ^ 3.

Answer: 0.002 g / cm ^ 3.
