Answer 1

Ответ:

ответ: 2,125

Объяснение:

n=V:Vm=18:22,4=0,8

M=m:n=43:0,8=54

D=Mr1(54):Mr2(16)=3,375

Answer 2

Calculating the Relative Density of an Unknown Gas

To calculate the relative density of an unknown gas (X) with respect to oxygen, we can use the following formula:

Relative Density = (Density of Gas X) / (Density of Oxygen)

The density of oxygen at standard conditions is approximately 1.429 g/L.

Given: - Volume of gas X (Vx) = 18 L - Mass of gas X (Mx) = 43 g

We can calculate the density of gas X using the formula: Density = Mass / Volume

Density of Gas X = Mass of Gas X / Volume of Gas X

Density of Gas X = 43 g / 18 L

Let's calculate the density of gas X first.

43 g / 18 L = 2.3889 g/L

Now, we can use the density of gas X and the density of oxygen to find the relative density of gas X with respect to oxygen.

Relative Density of Gas X = Density of Gas X / Density of Oxygen

Relative Density of Gas X = 2.3889 g/L / 1.429 g/L

Relative Density of Gas X ≈ 1.67

So, the relative density of the unknown gas X with respect to oxygen is approximately 1.67.
