There are 0.105 moles of gas are in a 1.25 L container.
Given the following data:
- Volume = 1.25 Liters.
- Temperature = 300 K
- Pressure = 2.07 atm
- Ideal gas constant, R = 0.0821L⋅atm/mol⋅K
To find how many moles (number of moles) of gas are in a 1.25 L container, we would use the ideal gas law equation;
[tex]PV = nRT[/tex]
Where;
- P is the pressure.
- V is the volume.
- n is the number of moles of substance.
- R is the ideal gas constant.
- T is the temperature.
Making n the subject of formula, we have;
[tex]n = \frac{PV}{RT}[/tex]
Substituting the given parameters into the formula, we have;
[tex]n = \frac{2.07(1.25)}{0.0821(300)}\\\\n = \frac{2.5875}{24.63}[/tex]
Number of moles, n = 0.105 moles.
Therefore, there are 0.105 moles of gas are in a 1.25 L container.
