Specific gravity of oxygen is?
Start with the molecular weight of oxygen, twice the atomic weight because it's O2. So the molecular weight is 32. Now at school you learn that a gram-mole of any gas occupies 22.4 litres. A gram-mole of oxygen weighs 32 grams (1 gram times the molecular weight). Therefore 32 grams of oxygen occupies 22.4 litres (at normal temperature and pressure). 22.4 litres of water (specific gravity = 1) weighs 22400 grams. Therefore the specific gravity is 32/22400 = 0.00142857 . . That's it!
How do you get gram molecular weight?
gram molecular weight = weight of one mole of the substance in grams for example 1 mole of water weighs 1 + 1 + 16 = 18 grams so gram molecularweight of water is 18g
How many pounds per pound-mole is equivalent to 1 gram per gram-mole?
To convert 1 gram per gram-mole to pounds per pound-mole, you would multiply by 0.00220462.
What is Mass of a gram mole of aluminum?
1 gram mole of Aluminium is about 27g.
What amount of oxygen require to react one gram calcium?
This is a relatively simple question that can be answered using simple stochiometry. If we assume a few things: a) that pure elements are reacting, b) that oxygen is in its stable diatomic form, and c) that they are reacting on a 1 to 1 mole ratio; then the math is as follows: 1 g.O2 x (1 mole O2 / 32 grams per mole) x (1 mole Ca / 1 mole O2) x (40.078 grams per mole / 1 mole Ca) = XXX.XX grams of Ca Thus the amount of calcium that will react on a 1 to 1 mole ratio with one gram of diatomic oxygen (O2) is 1.252 grams of calcium
What is 1 gram of atom?
mole
Why is the phrase the mass of 1 mole oxygen ambiguous?
The phrase "mass of 1 mole of oxygen" is ambiguous because it does not specify whether it is referring to the molar mass (atomic weight) of oxygen, which is approximately 16 g/mol, or the actual weight of 1 mole of oxygen atoms, which would be 16 grams. The context in which the phrase is used would determine the correct interpretation.
How much does a mole of diatomic oxygen weigh?
1 mole of a pure substance has a mass equal to its molecular mass (MM) so 1 mole of a substance x MM with oxygen its molar mass is 15.9994 so if your trying to find HALF then the equation would be 0.5 x 15.9994 therefore half a mole of oxygen gas will weigh exactly 7.9997 grams approx 8grams google usually helps with these sorts of equations aswell Love Maddi Leicester
How much does one mole of 0 weigh?
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.
How many times 1 mole of oxygen atom heavier than 1 mole of hydrgen atom?
A diamond is actually alot of carbon atoms interlinked with eachother. So a big diamond is actually only 1 molecule. Oxygen in its natural form is O2, 2 oxygen atoms linked together. So 1 mole of diamond could actually weigh as much as the earth, if the average weight of each diamond is 10 grams, while a mole of oxygen only weighs 32 grams.
How many times is 1 mole of oxygen atom heavier than 1 mole of hydrogen atoms?
The atomic weight of hydrogen is: [1,00784; 1,00811] and the conventional value for practical uses: is 1,008. The atomic weight of oxygen is: [15,99903; 15,99977] and the conventional value for practical uses is: 15,999.
Mass of 1 mol of oxygen atoms?
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...
