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.
What is a volume occupied by 0.02 mole of chlorine gas?
This volume is 0,449 L at 0 0C.
How many mole of helium are contained in a closed system holding 4.85 liters?
You need to specify temeprature and pressure At 0 0C and 1 atmosphere a mole of helium is approxomately 22.4 litres - 4.85 is about 0.21 mol
How do you convert mole fraction to volume fraction of liquid?
You need the balanced symbol equation for the reaction. The numbers in front of the formulae show the mole ratios. For example, in the thermal decomposition of calcium carbonate: CaCO3 --> CaO + CO2 The equation is balanced. The mole ratio between CaCO3 and CO2 is 1:1 because there is 1 mole of CaCO3 for every mole of CO2
How much does 75.0 L of helium weigh?
The weight of 75.0 L of helium depends on the temperature and pressure at which it is measured. At standard temperature and pressure (STP), which is 0°C and 1 atmosphere, the molar mass of helium is 4.0 grams per mole. Using the ideal gas law, we can calculate the weight by multiplying the molar mass of helium by the number of moles, which is the volume divided by 22.4 L (molar volume at STP). However, if the temperature and pressure are not at STP, additional information is needed to determine the weight.
