An ionic compound is a compound between a metal and a non metal where the metal (normally from group 1 or 2) transferrs an electron to the non metal ( most commonly from group 6 or 7) . this is so that both atoms have a full outer shell of electrons. the metal gains a positive charge and the non metal a negative charge. they are held together by electrostatic forces of attraction. an example would be sodium chloride (salt) sodium is in group 1 and chlorine in group 7 so sodium transfers one electron :)
Answer:
60 mL
Explanation:
200 mL = 0.2 L
We know that:
Molarity = Moles / Liters
So:
4.20 M = moles / 0.2 L
moles = 4.20 x 0.2 = 0.84
Then:
14.0 M = 0.84 moles / Liters
Liters = 0.84 moles / 14.0 M = 0.06 L
Since they want the answer in mL, convert 0.06 to get 60 mL
