Answer 1

Ответ:

n=3,72/22.4=0.16моль

Answer 2

Amount of Substance in 3.72 Liters of Natural Gas

The amount of substance in 3.72 liters of natural gas can be calculated using the ideal gas law, which states that the amount of substance (in moles) can be calculated using the formula:

n = PV / RT

Where: - n = amount of substance (in moles) - P = pressure (in atmospheres) - V = volume (in liters) - R = ideal gas constant (0.0821 L·atm/(K·mol)) - T = temperature (in Kelvin)

Given that the temperature and pressure are not provided, we can assume standard temperature and pressure (STP) for this calculation, which is 0°C (273.15 K) and 1 atmosphere respectively.

Using the ideal gas law at STP, we can calculate the amount of substance in 3.72 liters of natural gas.

Calculating the Amount of Substance:

Using the ideal gas law formula: n = PV / RT

At STP, the pressure (P) is 1 atmosphere and the temperature (T) is 273.15 K.

Given: - V = 3.72 liters - P = 1 atm - R = 0.0821 L·atm/(K·mol) - T = 273.15 K

Substituting the values into the formula: n = (1 atm) * (3.72 L) / (0.0821 L·atm/(K·mol) * 273.15 K)

n ≈ 0.153 moles

Therefore, 3.72 liters of natural gas at STP corresponds to approximately 0.153 moles of the substance.
