Data:
M (molarity) = 1.75 M (mol/L)
m (mass) = 35 g
MM (molar Mass) of NaCl = 58.44 g/mol
V (volume) = ? (in liters)
Formula:

Solving:





Moles of Li2CO3 = 1.53/73.891 = 0.0207 mole
Since HCl is in excess, amount of CO2 will depend on the limiting reagent which is Li2CO3.
∴Moles of CO2 = Moles of Li2CO3 = 0.0207.

Any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material. This is a true statement.
<h3>Features of natural materials</h3>
Natural materials are the physical matters that are made from plants, animals and ground(environment) which has not been subjected to any chemical processes for modification.
But any natural material that has undergone any chemical process which has been designed and manufactured to fulfil a particular purpose is called a synthetic material.
Therefore, any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material.
