In accordance with the stated assertion, 1 mol of Cacl₂will dissolve in the solution.
Chemists employ the mole, a highly significant unit of measurement. Like a dozen eggs implies twelve eggs, having a mole of anything indicates we had 602,214,076,000,000,000,000,000 of that item. For extremely tiny objects as electrons, polymers, or other particles, chemists must quantify using moles. A mole is defined as the mass of a material with the same numbers of elementary particles that are atoms in exactly 12.000 g of 12C.
You are aware that 1L of solution contains 2 moles of Cacl₂.
In 0.500 L of solution there are
0.500 L soln. * 2.0 mol of Cacl₂/1 L soln = 1 mol Cacl₂
