Limestone is easily weathered by acid rain. When rain mixes with gases such as sulfur dioxide and carbon dioxide in the atmosphere, acid rain is formed (sulfuric acid and carbonic acid respectively). When the rain precipitates and meets with limestone which is CaCO3, it is weathered a shown by the formulae; 2CaCO₃ (s) + H₂CO₃ → 2CaHCO3 (aq)
Geographical features formed as a result of weathering of limestone in rocks are caves, stalactites, and stalagmites.
<u>Answer:</u> The molarity of solution is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute (CAMP) = 0.0000000342 g
Molar mass of CAMP = 329.21 g/mol
Volume of solution = 1 L
Putting values in above equation, we get:
Hence, the molarity of solution is

49.5g
Explanation:
Mass of salt = 15g
Volume of solution = 1L
Volume of given solution = 3.3L
Unknown:
Mass of salt in the solution = ?
Solution:
Since we have been given the concentration of the salt in the solution, we can use it to solve the problem.
Concentration; 15g/L
Given;
In 1L of the solution we have 15g of salt,
In 3.3L of the solution we will have 3.3 x 15 = 49.5g
The salt is the solute and it represents the dissolved substances.
