Each molecule CoCl2 ionises in three single ions (1 Co2+ and 2 Cl- ions), so 0.27 mol CoCl2 gives 3 * 0.27 = 0.81 mole ions (0.27 mole Co2+ and 0.54 mole Cl- ions)

In moles of a substance dissolved in 1 L of water.
first determine the number ofmoles dissolved in given solution then .5 moles moles dissolved in 800g. as comparison with 1000g of water, we know 100g of water dissolve only.1 moles of a glucose so we .7moles of glucose dissolve in 800g.
