0.25 moles of oxygen there is 6.023/4×10^23 molecules.
What is the 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.
How many molecules are in 23.0 moles of oxygen?
Answer: The number of molecules of oxygen in 23 moles of oxygen is 1.385 x 1025 molecules of oxygen….
Why is O2 a molecule?
Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element – oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.
How many atoms of oxygen is present in 0.5 moles of oxygen?
⇒3.011×1023 number of molecules are present in 0.5moles of oxygen molecules. There are two oxygen atoms in a single oxygen molecule and this number of atoms is multiplied with the number of molecules. ⇒na=6.023×1023, hence the number of atoms present in 16g of oxygen molecule is 6.023×1023.
How many atoms are there in 0.25 mole of hydrogen * 2 points?
= 3.011 x 1023 atoms.
What is the mass of 0.5 mole of water?
Mass of 0.5 mole of water is 9g.
Is O2 2 moles of oxygen?
From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen.
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.
