Correct answer is magnesium bromide. This is an ionic compound with metal forming a positive ion - K+ and halogen forming a negative ion - Br-. When group 7 element form ions they have a suffix -ide. Bromine is the element and when it forms a negative ion bromine is called bromide with the suffix.
Magnesium gives 2 electrons and bromine can take only 1 electron, therefore 2 bromine atoms are needed. Therefore magnesium forms ionic bonds with 2 bromine atoms.
The compound is called magnesium bromide
To calculate the molar mass of substance, divide the number of moles by the given mass of substance.
The quantity of a substance is known as a mole. You can measure it in terms of grams, liters, atoms, molecules, or particles.
Use the substance's molar mass to convert between grams and moles. Divide the given mass by the number of moles to convert from moles to molar mass.
Using the formula, Number of moles = Given mass/ molar mass
The molar mass of a substance can be calculated as-
Molar mass = Given mass/number of moles

The ratio of phosphorous to oxygen is 2:5
<u>Explanation</u>:
- In a compound P2O5, the ratio of phosphorous to oxygen atoms is 2:5. Because there are two phosphorous atoms and five oxygen atoms. Both combined are called a P2O5.
- The elements of phosphorous and oxygen are added to P2O5. So P2O5 is called as phosphorous pentoxide. The element phosphorous will be added to oxygen and it will form a chemical reaction.
- This includes a change in the energy of P2O5. So the new energy will be produced.
pOH = -log(OH^(-)] = -log[9.50 × 10^(-9)] = 8.02
