How many atoms are in 2 moles of oxygen?
There are 6×6.022×1023 atoms in 2.00⋅mol NO2(g) .
What is K mole?
39.10 grams is the molar mass of one mole of K.
What is the mass of 2 moles of water?
One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.
How many molecules are in 2 moles O2?
So, 2moles of O2 contains 2× 6.023×10^23 molecule= 12.046 ×10^23 molecule .
How many atoms of oxygen are in 2 moles of N2O4?
(b) There are 8 moles of oxygen atoms in 2 moles of N2O4. (c) One molecule has a mass of 92 grams. (d) It is an ionic compound.
What is the mass of 1 gram mole of oxygen?
Solution — Mass of one mole of oxygen molecule (O2) = molecular mass of oxygen molecule (O2) in gram = 32 g.
What is the mass of 1 oxygen atom?
The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu. ⇒ 5.31 × 10–23g.
What is the mass of 2 A 0.2 mole of oxygen atoms B 0.5 mole of water molecules?
-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.
