A 0.400 M formic acid (HCOOH) solution freezes at -0.758°C. Calculate the Ka of the acid at that
temperature. (Hint: Assume that molarity is equal to
molality. Carry your calculations to three significant
figures and round off to two for Ka.)

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action

To calculate the molarity of a solution, you need to know the moles of solute and the
