The correct option is D.
Another way to write the chemical formula of magnesium phosphite is Mg3O6P2. The compound is made up of three atoms of magnesium, six atoms of oxygen and two atoms of phosphorus. The compound has anti fungal properties and it is also used as fertilizer. The compound is partially soluble in waster and it can be yellow or green in color.
An ion differs from an atom in that it has a net electrical charge, either positive or negative, due to the loss or gain of electrons.
An ion differs from an atom in that it has a net electrical charge. This charge is either positive or negative, resulting from the loss or gain of electrons by the atom. When an atom loses electrons, it becomes positively charged and forms a cation. On the other hand, when an atom gains electrons, it becomes negatively charged and forms an anion.
For example, let's consider sodium (Na) and chloride (Cl) atoms. Sodium has 11 protons and 11 electrons, making it neutral. However, when it loses an electron, it becomes a sodium ion (Na+), which now has 11 protons and 10 electrons, giving it a +1 charge. Chloride, on the other hand, has 17 protons and 17 electrons, making it neutral. But when it gains an electron, it becomes a chloride ion (Cl-), which now has 17 protons and 18 electrons, giving it a -1 charge.
So, while an atom is electrically neutral, an ion has a charge due to the loss or gain of electrons.

According to the concept of Avogadro's number, there are 1.499 moles of hydrogen gas contained in 9.03 x 10²³ molecules.
Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.
It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .
According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.
Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number
Number of moles is calculated from Avogadro's number as, 1 mole=6.023×10²³ molecules , thus 9.03×10²³ molecules will have 9.03×10²³ /6.023×10²³=1.499 moles.
Thus, there are 1.499 moles of hydrogen gas contained in 9.03 x 10²³ molecules.
