Hint: According to the equation, one mole of produces one mole of .Molar mass is the sum of the atomic masses of elements present in the compound.The number of molecules in one gram-mole of a substance, defined as the molecular weight in grams, is , a quantity called the Avogadro constant.
Complete step by step solution:
The molecular mass of is = 100.0869
The molecular mass of is = 110.098
1 Mole of any substance is equals to particles
In the above reaction, if we take 1gram of it will contain molecules and similarly 1 mole of will produce 1 mole of CaCl2 that is molecules while reacts with hydrochloride.
Since we use 2.5 g of CaCO3
= 2.75 g
The 2.75 g mass of calcium chloride formed while reacting 2.5 g Calcium Carbonate with excess hydrochloride.
Note: One mole is defined as the amount of substance containing the same number of entities as the number of atoms in a sample of pure weighing exactly 12 grams. The number of entities composing a mole has been experimentally determined to be .
