Global warming, the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. Global warming and its effects, such as more intense summer and winter storms, are also referred to as climate change.
Answer: The molar concentration of
in the solution is 0.2 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,
n= moles of solute =
= volume of solution in ml = 100 ml


As 1 mole of
gives 2 moles of 
Thus 0.1 moles of
gives =
moles of 
The molar concentration of
in the solution is 0.2 M
