Is Amu same as g mol?
The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol). Although mass can be expressed as both amu and g/mol, g/mol is the most useful system of units for laboratory chemistry.

How do you calculate percentage of CaCO3 in CA?
You take the atomic mass of calcium over the atomic mass of CaCO3 and multiply it by 100 to get the percentage.
How do you calculate AMU?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
Why is Amu used instead of grams?
Because atoms are ridiculously small. which is immeasurably small. We don’t care for masses that small because we physically can’t see or measure it. Instead, we care for masses we can touch, like 1.000 g or 12.50 g .

Why is calcium’s symbol CA?
Calcium is all around us. Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table. It was first isolated in 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide.
Does CA NO3 2 form a precipitate?
As that product forms, it emerges, or precipitates, from the solution as a solid. It is a precipitate. Ca(NO3)2(aq) + Na2CO3(aq) → CaCO3(s) + 2NaNO3(aq) One of the goals of this section is to help you to visualize the process described by this equation.
Why is CA NO3 2 soluble in water?
Calcium nitrate is a compound that is highly soluble in water. When calcium nitrate dissolves in water, the heat is absorbed. This absorption of heat makes it easily dissolved in water.
