How many total ions are in 2.95 g of magnesium sulfite?

Approximately , which is approximately particles.

Explanation:

Formula of magnesium sulfite: .

Look up the relative atomic mass of . , and on a modern periodic table:

The ionic compound consist of magnesium ions and sulfite ions .

Notice that and combine at a one-to-one ratio to form the neural compound . Therefore, each formula unit would include one ion and one ion (that would be two ions in total).

Calculate the formula mass of one such formula unit:

.

In other words, the mass of one mole of formula units (which includes one mole of ions and one mole of ions) would be .

Calculate the number of moles of such formula units in that of :

.

There are two moles of ions in each mole of formula units. Therefore, that of formula units would include approximately of ions.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
