Answer 1

Ответ:

Объяснение:

Сравните число молекул в одинаковых объемах кислорода O₂ и угарного газа CO. Молярная масса кислорода 0,032 кг/моль, угарного газа 0,028 кг/моль.

Дано:

V₁ = V₂

M₁ = 0,032 кг/моль

M₂ = 0,028 кг/моль

_________________

N₁ - ?

N₂ - ?

Вспомним закон Авогадро.

Закон Авогадро: в равных объёмах различных газов при одинаковых условиях (температуре и давлении) содержится одинаковое число молекул.

Поскольку объемы одинаковые то и число молекул кислорода равно числу молекул угарного газа.

Answer 2

Comparison of the Number of Molecules in Equal Volumes of Oxygen and Carbon Monoxide Gases

To compare the number of molecules in equal volumes of oxygen (O2) and carbon monoxide (CO) gases, we need to use the ideal gas law, which states that the number of molecules in a gas is directly proportional to its molar mass and inversely proportional to its volume.

The molar mass of oxygen (O2) is given as 0.032 kg/mol, and the molar mass of carbon monoxide (CO) is given as 0.028 kg/mol.

Using the ideal gas law, we can calculate the number of molecules in equal volumes of these gases.

The ideal gas law is given by the equation:

PV = nRT

Where: - P is the pressure of the gas - V is the volume of the gas - n is the number of moles of the gas - R is the ideal gas constant (8.314 J/(mol·K)) - T is the temperature of the gas in Kelvin

In this case, we are comparing equal volumes of gases, so the volume (V) can be considered the same for both oxygen and carbon monoxide.

Let's assume the volume is 1 liter (1 L) for simplicity.

Using the ideal gas law, we can rearrange the equation to solve for the number of moles (n):

n = PV / RT

Since the volume (V) and temperature (T) are the same for both gases, we can compare the number of moles (n) directly.

Now, let's calculate the number of moles of oxygen (Nк) and carbon monoxide (Nчг) gases.

For oxygen (O2): - Molar mass (Mк) = 0.032 kg/mol - Volume (V) = 1 L - Temperature (T) = to be determined

For carbon monoxide (CO): - Molar mass (Mчг) = 0.028 kg/mol - Volume (V) = 1 L - Temperature (T) = to be determined

To calculate the number of moles, we need to know the temperature of the gases. Could you please provide the temperature at which we are comparing the gases?
