Explanation:
hydrogen bonds are initially weak and collectively strong because they are partially positive ions
Most tennis balls are usually hollow, while golf balls are not. Therefore a golf ball contains more mass.

Since 1 mole of any element contains 6.0221023 atoms, a mole of carbon and a mole of oxygen will have the same number of atoms.
<h3>Is a mole of oxygen equivalent to a mole of carbon?</h3>
Answer and justification The molar mass of carbon differs from the molar mass of oxygen, hence this assertion is untrue. As a result, one mole of oxygen and one mole of carbon cannot have the same mass.
<h3>What kind of link unites carbon and oxygen?</h3>
A polar covalent link between carbon and oxygen is known as a carbon-oxygen bond. With six valence electrons, oxygen likes to either share two of them in a bond with carbon, leaving the remaining four unoccupied.

Given information : Sample of 
We need to find the moles of Chlorine in the given sample.
We can say that we need to find moles from the given atoms.
Relation between mole and atom is given by : 
Where 
is Avogadro number.
On solving the above equation , atoms(unit) gets cancelled out and we get 0.0286 mol.
In the given sample the moles of Chlorine (Cl) is 0.0286 mol , so option A is correct.
