Answer:
Calculating this, we get:
x ≈ 0.0081 moles
Therefore, there are approximately 0.0081 moles of oxygen in 0.181 liters.
Step-by-step explanation:
To determine the number of moles in 0.181 liters of oxygen, we need to use the concept of molar volume. Molar volume is the volume occupied by one mole of any gas at standard temperature and pressure (STP), which is defined as 0 degrees Celsius and 1 atmosphere of pressure.
At STP, one mole of any gas occupies 22.4 liters of volume.
To find the number of moles in 0.181 liters of oxygen, we can set up a proportion:
0.181 liters oxygen / 22.4 liters oxygen = x moles / 1 mole
Cross-multiplying, we get:
0.181 liters oxygen * 1 mole = 22.4 liters oxygen * x moles
Simplifying the equation, we have:
0.181 = 22.4 * x
Dividing both sides by 22.4, we find:
x = 0.181 / 22.4
