One mole of atoms of oxygen has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 1023 atoms of oxygen.
What is the value of one mole of oxygen *?
The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.
What is the mass of 1 mole of oxygen molecule?
EXPLANATION: One mole of atoms of oxygen has a mass of 16 g. One mole of oxygen gas has a mass of 32 g.
What is the mole of H2?
The mass of one mole of H2 is 2.01588 grams but some sources also list it as 2.016 grams. A molecule of H2 is formed when two hydrogen atoms bond…
How many liters are in 1 mole of O2?
The molar volume of an ideal gas is ~22.4 liters per mole (we’ll consider O2 to be an ideal gas for these purposes, and 22.4 is an approximation that varies with temperature, it’s 22.414 at 0C).
What is the mass of 1 mole?
The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
How do you convert to moles?
A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.
How many grams are in 1 mole of oxygen?
For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 1023 oxygen atoms. Similarly, for one gram atomic weight of silicon with atomic weight of 28 grams, one mole of silicon still contains 6.022 × 1023 silicon atoms.
What is the mole of nh3?
17.03052 g/mol .
What is the mole of helium?
The molar mass is the mass of one mole of an element and is found on the periodic table. If we look this number up for helium, we find that helium has a molar mass of 4.0 grams per mole. So one mole of helium has a mass of 4.0 grams.
What is a mole of co2?
The molecular mass of carbon dioxide is 44.01amu. … One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g. The molar masses are 44.01g/mol and 78.04g/mol respectively.
How many liters is 2 moles of oxygen?
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 is 1l in grams?
Since there are 1,000 grams in a kilogram, the answer is that 1 liter of water weights 1,000 grams.
How do I calculate moles?
