Which aqueous solution of kl freezes at the lowest temperature? a) 2 mol of kl in 1,000. g of water b) 1 mol of kl in 1,000. g of water c) 2 mol of kl in 500. g of water d) 1 mol of kl in 500. g of water

c) 2 mol of Kl in 500. g of water

Explanation:

Colligative properties such as melting and boiling points and osmotic pressure all depend on the amount of solute present. The more the concentration of solute present, the greater the degree of display of colligative properties by a solution

Considering the options given, 2 mol of Kl in 500. g of water has the highest concentration and is expected to freeze at the lowest temperature.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
