The answer is: A - Strong base

Explanation:

The pH scale goes from 1 - 14 with 1 being the most acidic, 7 being neutral, and 14 being the most basic. Since 13 is right below 14 (which is the most basic), it is a strong base.

How many moles of kf are contained in 244 ml of 0.135 m kf solution? the density of the solution is 1.22 g/ml?

galben [10]

The Molarity of a solution = number of moles / volume.
Volume = 244ml = 0.244L
So it follows that number of moles = Molarity * volume
Number of moles = 0.135 * 0.244 = 0.03945.
Hence the number of moles = 0.03945
