What is the volume occupied by 2 moles of a gas?
David G. Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .
What are the 5 assumptions of an ideal gas?
The kinetic-molecular theory of gases assumes that ideal gas molecules (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) have an average kinetic energy proportional to the ideal gas’s absolute temperature.
How do you convert moles of gas to volume?
Converting from volume (liters) to moles: Divide your initial volume by the molar volume constant, 22.4 L. Converting from moles to volume (liters): Multiply your mole value by the molar volume constant, 22.4L.
What volume will 2 moles of oxygen gas occupy at STP?
so 2mol O2 occupies 44.8L of volume at STP.
How do you calculate moles of gas?
Multiply the volume and pressure and divide the product by the temperature and the molar gas constant to calculate moles of the hydrogen gas. In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles.
What is the volume in liters of 3.75 moles of O2 gas?
What is the volume in liters of 3.75 moles of O2 gas at STP? Answer : The volume of oxygen gas is 84.0 liters.
What is the weight of 0.1 mole of na2co3?
Thus, the weight of 0.1 mole sodium carbonate is 10.6g.
What is ideal gas behavior?
For a gas to be “ideal” there are four governing assumptions: The gas particles have negligible volume. The gas particles are equally sized and do not have intermolecular forces (attraction or repulsion) with other gas particles. The gas particles move randomly in agreement with Newton’s Laws of Motion.
What is called an ideal gas Why?
Ideal gases are defined as having molecules of negligible size with an average molar kinetic energy dependent only on temperature. At a low temperature, most gases behave enough like ideal gases that the ideal gas law can be applied to them. An ideal gas is also known as a perfect gas.
What is the ideal gas law used for?
The ideal gas law can be used to calculate volume of gases consumed or produced. The ideal-gas equation frequently is used to interconvert between volumes and molar amounts in chemical equations.
