How many total ions are present in 347g of cacl2?

In 1 mole of , there are 3 moles of ions, 1 mole of Ca^{2+} and 2 mole of .

Molar mass of is 110.98 g/mol. Calculating number of moles from given mass as follows:

Thus, number of moles of ions will be .

Since, 1 mole of any substance has units of that substance where  is Avogadro's number.

Thus, 9.38 mol of ions will have number of ions.

Therefore, total number of ions in 347 g of is  .

so what is the problem with your lab report and whats the subject of the lab report? i will you
