Best Answer

The relative molecular mass of magnesium chloride is approximately 60. The molar mass is therefore 60g per mole. Therefore there is 0.42mol of formula units in 2.5 grams.

The formula mass of MgCl2 is 24.3 + 2(35.5) = 95.3Amount of MgCl2 = 2.5/95.3 = 0.0262mol

There are 0.0262 moles of formula unit in 2.5 grams of magnesium chloride.

To get the number (not in moles), multiply the amount in moles by the Avogadro's constant.

Does 1 mole of sodium chloride and 1 mole of magnesium chloride has same number of ions?

No: Each "mole", more precisely called "formula mass", of sodium chloride contains two ions, as shown by its formula NaCl, but each formula mass of magnesium chloride has three ions as shown by its formula MgCl2. This is true because sodium cations have only one positive electric charge unit, magnesium cations have two electric charge units, and chloride ions have one negative electric charge unit each.
