Question

6. Тыныштықта бір рет тыныстаған жасөспірімнің өкпесіне шамамен 300 мл (онда 0,0026 моль оттек бар) ауа кiредi. Осы оттектiн 22%-ы өкпеге сіңіріліп, қалғаны сыртқа шығады. Бір рет тыныстағанда жасөспiрiм қанша молекула оттекті жұтады? Жауабы: 3,44-1021 Неше молекула оттек екпеге сiңiрiлмейдi?​

Answer 1

Calculation of Molecules in a Gas Sample

To calculate the number of molecules in a gas sample, we can use the ideal gas law equation, which states that:

PV = nRT

Where: - P is the pressure of the gas - V is the volume of the gas - n is the number of moles of gas - R is the ideal gas constant - T is the temperature of the gas in Kelvin

In the given question, we are provided with the following information: - The volume of the gas sample is 300 mL, which is equivalent to 0.3 L. - The number of moles of the gas sample is 0.0026 mol. - 22% of the gas sample is transferred to another container.

To find the number of molecules in the gas sample, we need to calculate the number of moles of the gas sample using the given information.

Using the ideal gas law equation, we can rearrange it to solve for n:

n = PV / RT

Let's calculate the number of moles of the gas sample:

Given: - P = pressure of the gas (not provided) - V = volume of the gas sample = 0.3 L - n = number of moles of the gas sample = 0.0026 mol - R = ideal gas constant (8.314 J/(mol·K)) - T = temperature of the gas (not provided)

Since the pressure and temperature of the gas are not provided, we cannot calculate the exact number of molecules in the gas sample without this information.
