(a) The atomic mass of oxygen (O) = 16 u. The mass of 1 mole of oxygen atoms = 16g. Hence, 0.2 mole of oxygen atom = 3.2 g.
What is the mass of 0.2 moles of oxygen?
-To calculate the mass of 0.2 moles of oxygen atom we should know the mass of a single atom of oxygen that is 16. -Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.
What is the mass of a mole of O2?
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
What is the mass of 0.5 mole of oxygen?
0.5 moles of O2 weighs 16 grams.
What is the mass of 0.1 mole of oxygen atoms?
Mass of 0.1 mole of oxygen is = 16 * 0.1 =1.6 g.
What is the mass of 0.5 moles?
Mass of 0.5 mole of water is 9g.
What is the mass of 0.2 mole of oxygen atoms Brainly?
The molecular weight of Oxygen is twice the atomic weight (since Oxygen is diatomic)=16*2=32 . Thus, the mass of 1 mole of Oxygen is 32g. Therefore, the mass of 0.2 moles of Oxygen is 32*0.2= 6.4 g(Answer).
How many grams is 2 moles of oxygen?
Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..
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).
How do you find the mass of oxygen?
Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule. O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.
What is the mass of 0.2 mole of h2?
Weight of 0.2 mole H2 gas = 2(Mol. Mass) x 0.2 = 0.4 g.
What is the no of molecules and no of atoms in 0.5 moles of oxygen?
What is the mass of 0.6 mole of oxygen atom?
12.8 grams. The relative atomic mass of oxygen is 16. Oxygen exists as a diatomic molecule, O2 . Thus the relative molecular mass of oxygen is 32.
What is the mass of 0.2 g of oxygen atoms?
Answer Expert Verified
a) Well, first of all 16 u = the mass of 1 mole of O2 atom. That is it weighs 16 g. ∴ Mass of 0.2 mole of O2 atoms = 16*0.2 = 3.2 u.
What is the mass of 0.2 mole of carbon atom?
Therefore 0.2 moles of carbon = 0.2 X 12 = 2.4 g.
What is the mass of 0.5 gram atom of oxygen?
Mass of 0.5gram atom of oxygen is 8gm
