Answer 2

5,6 liters of oxygen corresponds to a certain amount of substance. However, the provided search snippets do not directly answer the question. Therefore, I will provide a general explanation.

To determine the amount of substance that corresponds to a given volume of a gas, we need to use the ideal gas law. The ideal gas law states that the amount of substance (n) is directly proportional to the volume (V) of the gas, at constant temperature and pressure. The equation can be written as:

n = PV/RT

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

To calculate the amount of substance, we need to know the pressure and temperature of the gas. Without this information, it is not possible to determine the exact amount of substance that corresponds to 5.6 liters of oxygen.

If you have the pressure and temperature values, I can help you calculate the amount of substance using the ideal gas law.
