The normal freezing polnt of a certaln liquld X Is -8.10 °C, but when 28.8 g of barlum hydroxide (Ba(OH),) are dissolved in 700. g of X the solution freezes at -9.3 °C Instead. Use this Information to calculate the molal freezing polnt depression constant K, of X. Be sure your answer i rounded to the correct number of slgnificlant digits. °C•kg mol

An experiment was conducted to determine the effect of glucose on the freezing point of water. Experimental data showed thatthe freezing point depression of water in solution was –2.6°C when 1.0 g of glucose was dissolved in 10g of solvent. Calculatethe expected freezing point for such solution and compare the expected freezing point to the value found experimentally. Give aplausible explanation for any discrepancies. (M.W. of glucose= 180.16g/mol; i=1). Show all your work.

If 90 grams of NaNO3 is completely dissolved at 10°C is the solution saturated, unsaturated or supersaturated ?

The normal boiling point of a certain liquid X is 111.60 °C, but when 0.13 kg of potassium bromide (KBr) are dissolved in 900. g of X the solution boils at 113.6 °C instead. Use this information to calculate the molal boiling point elevation constant K, of X. Round your answer to 2 significant digits. °C-kg K, mol
