0.5mv^2
0.5 times 40 times 3^2
The kinetic energy is 180
Explanation:
Molecular mass is defined as the sum of atomic masses of all the atoms present in a given compound.
For example, molecular mass of is as follows.
=
=
= (12 + 4) g/mol
= 16 g/mol
Hence, the molecular mass of is 16 g/mol.
Therefore, we can conclude that the sum of the atomic masses of all the atoms in a formula for a covalent compound is the molecular mass.
Answer:
by taking other atoms that have one shell and putting it i the spot that they need t in
