Calculate the number of moles of cl atoms in 1.81×10^24 formula units of magnesium chloride, mgcl2.

The number of moles of Chlorine atoms in given formula units of magnesium chloride are 6 moles.

Explanation:

Formula unit is defined as lowest whole number ratio of ions in an ionic compound. It is calculate by multiplying the number of moles by Avogadro's number which is

We are given:

Number of formula units of magnesium chloride =

By applying unitary method, we get:

If number of formula units are present in 1 mole of a compound.

So, number of formula units will be present in of magnesium chloride.

For the given compound magnesium chloride:

As, 1 mole of magnesium chloride contains 1 mole of magnesium atom and 2 atoms of chlorine atoms.

So, 3 moles of magnesium chloride will contain of magnesium atoms and of chlorine atoms.

Hence, the number of moles of Chlorine atoms in given formula units of magnesium chloride are 6 moles.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
