An ammonia molecule is made up of one nitrogen and 3 hydrogen atoms, it has a formula nh3. what is the mass of one more ammonia? **hint find the molar mass of ammonia by adding up all of the masses of the elements in the compound.

The molar mass is the sum of the mass of all the atoms of a particular molecule.

The unit  of molar mass is grams per mole.

The atomic mass of H = 1.00

The atomic mass of N = 14.00

The molar mass of ammonia = atomic mass of N + 3 x (atomic mass of H)

                                                = 14.00 + 3 x (1.00) = 17.00

Therefore the molar mass of ammonia is 17g/mol

The correct answer is  17g/mol.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
