Question

Густина газу за воднем 32. Яка маса 1 л цього газу. Яка його густина за повітрям?

Answer 1

Дано: D(H2)=32

Найти: M(газ), D(воздух) - ?

Решение

1)D(H2)=M(газ)/M(H2) ;

M(газ) = D(H2)*M(H2) = 32 * 2 = 64(г/моль)

2)D(воздух) = M(газ)/M(воздух) = 64/29 ~2.2

Ответ: M(газ) = 64г/моль ; D(воздух) = 2.2

Answer 2

Gas Density and Mass Calculation

The density of a gas can be calculated using the formula density = mass / volume. Given that the density of the gas is 32 g/L, we can calculate the mass of 1 L of this gas and its density compared to air.

To find the mass of 1 L of this gas, we can use the formula mass = density * volume. Substituting the given density of 32 g/L and the volume of 1 L, we get:

mass = 32 g/L * 1 L = 32 g

So, the mass of 1 L of this gas is 32 grams.

Gas Density Compared to Air

To find the density of this gas compared to air, we can use the formula density ratio = gas density / air density. The density of air is approximately 1.2 g/L at room temperature and pressure.

Substituting the given gas density of 32 g/L and the air density of 1.2 g/L, we get:

density ratio = 32 g/L / 1.2 g/L ≈ 26.67

So, the density of this gas compared to air is approximately 26.67 times greater.
