1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.

What is one mole of carbon dioxide?

Moles of what? Air (what you breathe) is not a consistent substance. It consists of nitrogen, oxygen and other things. If you mean moles of oxygen, we need to know the density. At 0*C, the density of oxygen is 1.429 g/L. We convert this to the volume we have and then divide it by the molar value of oxygen, 16 g/mol, to give us 4.47 x 10^4 mols.


How much 1 mol of O2 gas?

One mole of O₂ gas occupies approximately 22.4 liters at standard temperature and pressure (STP), which is 0 degrees Celsius and 1 atmosphere of pressure. The molar mass of O₂ is about 32 grams, meaning that 1 mole of O₂ weighs 32 grams. Thus, under STP conditions, 1 mole of O₂ gas will have both a specific volume and mass.


If you have a balloon filled with one mole of gas at zero degrees Celsius at a pressure of one atmosphere how many gas particles do you have?

At standard temperature and pressure (0 degrees Celsius and 1 atmosphere), one mole of any ideal gas contains approximately 6.022 x 10²³ particles, which is known as Avogadro's number. Therefore, if you have a balloon filled with one mole of gas at these conditions, you have about 6.022 x 10²³ gas particles in that balloon.


Under what sets of condition will a 0.50 mole sample of helium occupy a volume of 11.2 liters?

A 0.50 mole sample of helium will occupy a volume of 11.2 liters under standard temperature and pressure (STP) conditions, which are 0 degrees Celsius (273.15 K) and 1 atmosphere pressure. At STP, one mole of any gas occupies a volume of 22.4 liters.


What is a volume occupied by 0.02 mole of chlorine gas?
