Question

11. Массасы 177,5 г хлордың (қ.ж.) алатын көлемі: А) 22,4 л. В) 5,6 л. C) 112 л. D) 56 л. E) 11,2 л. Шыгарып бериндерши

Answer 1

n=m/M

n(Cl2) = 177,5/71 = 2,5 моль

V=n×Vm

Vm = 22,4 л/моль

V(Cl2) = 2,5 × 22,4 = 56 л

Ответ: D)

Answer 2

Массасы 177,5 г хлордың (қ.ж.) алатын көлемі:

Массасы 177,5 г хлордың (қ.ж.) алатын көлемін табу үшін хлордың қ.ж. массасын қосып, алатын көлемін табу керек.

Unfortunately, I couldn't find a direct answer to your question in the search results. However, I can provide you with some information about the concept of molar volume and how it can be calculated.

Molar volume is the volume occupied by one mole of a substance at a given temperature and pressure. It is usually expressed in liters per mole (L/mol). The molar volume of a substance can be calculated using the ideal gas law equation, which relates the pressure, volume, and temperature of a gas:

V = (n * R * T) / P

Where: - V is the volume of the gas in liters - n is the number of moles of the gas - R is the ideal gas constant (0.0821 L·atm/(mol·K) or 8.314 J/(mol·K)) - T is the temperature in Kelvin - P is the pressure in atmospheres

To calculate the molar volume of chlorine gas (Cl2), you would need to know the number of moles, temperature, and pressure. Without this information, it is not possible to determine the molar volume of 177.5 g of chlorine gas.

If you have any additional information or specific values for temperature and pressure, I would be happy to assist you further in calculating the molar volume.
