Answer:
The chlorine from the chlorofluorocarbons reacts with free molecules of oxygen causing a stop in ozone production. ... Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone.
The color produced by one milligram of platinum cobalt in one liter of dissolved water is fixed as one unit of color in platinum-cobalt scale.
Explanation:
The given data is as follows.
= 3 M,
= ?
= 10 M,
= 10.0 ml
Therefore, calculate the volume of given solution as follows.
=
Now, putting the given values into the above formula as follows.
=
=
= 33.3 ml
or, = 0.033 L (as 1 ml = 0.001 L)
Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.
Molarity = 
3 M = 
mass = 3.96 g
Therefore, we can conclude that mass of NaOH is 3.96 g.
