2. The active ingredient in many commercial antifreezes is ethylene glycol (C,H,O2). If you wish to protect your radiator down to -25 °F, how many grams of ethylene gly- col should you add to each liter of water? First convert the temperature to degrees Celsius, use the K; value of 1.853 °C/molal for water, and recall that the density of water is 1.00 g/mL.

A certain substance X has a normal freezing point of -3.1 °C and a molal freezing point depression constant - 1 K=7.46 °C-kg•mol A solution is prepared by dissolving some urea CO in 750. g of X. This solution freezes at -7.1 °C. Calculate the mass of urea that was dissolved. Round your answer to 2 significant digits. olo Ar

Sequence the steps required for a sodium chloride crystal to dissolve in water. (Enter numbers 1 - 6)   The charged ends of water molecules attract the positive Na ion and the negative Cl ions. The ions from the crystal break away from the surface. Water molecules collide with the surface of the crystal. NaCl crystals are placed in water Solvation continues until the entire crystal has dissolved. The attraction between the dipoles and the ions are stronger than the attractions among the ions in the crystal.

The boiling point of water is 100.00 °C at 1 atmosphere. A student dissolves 11.57 grams of manganese(II) iodide, MnI, (308.7 g/mol), in 221.5 grams of water.
