Question

What is the molar mass of ${\left( {N{H_4}} \right)_2}C{O_3}$?

Answer 1

We have to know that the molar mass of a chemical compound is equal to the mass of the sample which is present in the compound and it should be divided with the amount of substance present in the sample. And the molecular weight is another term of molar mass which is used for the molecular compounds. And this is an intensive property. Because, it will not depend on the size of the sample. The molar mass is expressed in terms of kg/mol.

Complete answer:
We need to know that the ammonium carbonate is a chemical compound having the formula ${\left( {N{H_4}} \right)_2}C{O_3}$ . And the molar mass of ammonium carbonate is equal to$96g/mol$. It can be found out by adding the molecular mass of each element present in the sample. Hence here number of nitrogen is equal to two, number of hydrogen is equal to four, number of carbon is equal to one and number of oxygen is equal to three. Therefore,
$Nitrogen = 14 \times \left( 2 \right) = 28$
$Hydrogen = 1 \times \left( 4 \right) = 4$
$Carbon = 12 \times \left( 1 \right) = 12$
$Oxygen = 16 \times \left( 3 \right) = 48$
Here we have to add each of the masses. Hence, we will get the value of molar mass of ammonium carbonate.
$Molarmass = 28 + 8 + 12 + 48 = 96g/mol$

Note:
We have to know that ammonium carbonate is a chemical compound having a molar mass equal to $96g/mol$ . The ammonium carbonate is a white crystalline salt and it is non – toxic in nature. And this compound is also called baker’s ammonia. This ammonium carbonate will be decomposed in the hot water and it will be soluble in water. And it is mainly used in flat baked goods as a leavening agent. Sometimes, it will affect our skin very badly and it may cause some irritations to our human skin.
