Answer : 0.125 M
Explanation : The definition of osmotic pressure is "<span><em>the pressure can be applied on a pure solvent to prevent it passing into a given solution by osmosis</em>".
</span>
So according to this definition, osmotic pressure can be called as directly proportional to the concentration of the solution and hence the pressure can also be directly proportional to the concentration.
Hence, if pressure is getting decreased from 28 to 7 it means it got decreased by 4 times;
28 / 7 = 4 that means;
So the concentration will be also decreased by 4 times so, 0.50 / 4 = 0.125 M
Option A is the correct option.
In terms of the collision theory, increasing the concentration of a reactant increases in the number of collisions between the reacting species per second and therefore increases the reaction rate.
CO3 = carbonate ion
So, CaCO3 = calcium carbonate
Other name for CaCO3 are: Limestone and Marble
