Answer 2

To determine the number of molecules (X*10^23) in 10 liters of oxygen gas, we can use the ideal gas law equation. The ideal gas law equation is given by:

PV = nRT

Where: P = pressure of the gas V = volume of the gas n = number of moles of the gas R = ideal gas constant T = temperature of the gas

In this case, we are given the volume of the gas (10 liters) and we need to find the number of molecules (X*10^23). To do this, we need to calculate the number of moles of oxygen gas using the ideal gas law equation.

The ideal gas constant (R) is a constant value equal to 0.0821 L·atm/(mol·K). The temperature (T) is not given, so we will assume it to be at standard temperature and pressure (STP), which is 273.15 K.

Let's calculate the number of moles of oxygen gas using the ideal gas law equation:

PV = nRT

n = (PV) / (RT)

Substituting the given values: P = pressure of the gas (not given) V = volume of the gas (10 liters) R = ideal gas constant (0.0821 L·atm/(mol·K)) T = temperature of the gas (273.15 K)

n = (P * 10) / (0.0821 * 273.15)

Since the pressure of the gas is not given, we cannot calculate the exact number of moles of oxygen gas. Therefore, we cannot determine the number of molecules (X*10^23) in 10 liters of oxygen gas.

Please note that the answer may vary depending on the pressure of the gas.
