Determine the formula mass of NH3. Round your answer to 2 decimal places.

17.03g/mol

Explanation:

The formula mass is the molar mass of a given compound.

 Atomic mass of N = 14.0067g/mol

                            H  = 1.0079g/mol

Now;

  Insert the parameters and solve;

   Formula mass = 14.0067 + 3( 1.0079)  = 17.03g/mol

The formula mass of the compound is 17.03g/mol

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

if you're asking what comes out, it's steam.
