Question

2 моля газа при температуре=22,7 градусов занимает обьем=8,3.Расчитайте давление газа.

Answer 1

PV=nRT
P=nRT/V
Всё подставишь: n - кол-во вещ-ва (моль); R - постоянная величина = 8,3; T - температура в КЕЛЬВИНАХ; V - объём в м³; P -давление!

Answer 2

Calculating the Pressure of a Gas

To calculate the pressure of a gas, we can use the ideal gas law formula:

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 - T is the temperature of the gas in Kelvin

First, we need to convert the given temperature from Celsius to Kelvin using the formula:

T(K) = T(°C) + 273.15

Given: - Temperature (T) = 22.7 °C - Volume (V) = 8.3 L

Let's calculate the pressure of the gas using the ideal gas law formula.

Calculation

1. Convert the temperature from Celsius to Kelvin: - T(K) = 22.7 + 273.15 = 295.85 K

2. Now, we can calculate the pressure using the ideal gas law formula: - PV = nRT - Since the number of moles (n) and the ideal gas constant (R) are not provided, we'll assume the number of moles and the ideal gas constant to be 1 for simplicity.

- P = (nRT) / V - P = (1 * 0.0821 * 295.85) / 8.3 - P ≈ 2.91 atm

Answer

The pressure of the gas at a temperature of 22.7 °C and a volume of 8.3 L is approximately 2.91 atm.
