Answer:
Explanation:
1. Add the atomic mass of all the elements.
39+55.8+12+14= 120.8
2.Divide atomic mass of potassium by total atomic mass
2. Multiply by 100

The smallest unit of a compound that still has the properties of the compound is called a molecule.
Molecules are made up of two or more atoms. It has the physical and chemical properties of a compound.
The atoms in a molecule are connected by different chemical bonds. Intramolecular forces hold the atoms together in a molecule. Types of intermolecular forces are London dispersion forces (LDF), dipole-dipole interactions, and hydrogen bonding.
There are different types of molecules like diatomic molecules, homonuclear diatomic molecules, heteronuclear, and polyatomic molecules.
Examples of molecules include CO, CL2, NH3, O3, etc.

Answer:
The student is Incorrect
Explanation:
Even if you break a magnet the poles still remains same. There is no
difference in the magnet Both north and south pole will be there even if you
cut it in to small pieces when you cut it into pieces, if suppose you break 2
magnets and put north and north together it will repel whereas if there are
different poles like north and south it will attract, so even if you break one
single magnet the different poles will attract, Hence the student is incorrect.
