You have 350.0mL of 0.200M aqueous KCIO4. Which of the following statements are true?

There may be more than one correct answer!

-For every liter of solution, there is 0.200 moles ofKCIO4.

-Water is the solvent.

-If you add KCIO, to the solution, the molaritywill decrease.

-For every 0.200 liters of solution, there is 1 mole ofKCIO4.

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %
