What is a positive acceleration ?
<h2>If the velocity of an object increases with time, its acceleration is positive.
<h2 /><h2>What is a zero acceleration ?
<h2>Zero acceleration is an acceleration, just with zero magnitude. Motion with constant velocity is just a special case of motion with uniform acceleration.
<h2>What is a negative acceleration ?
<h2>A negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity. ... And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

Number of molecules NH₃ = 4.45 x 10²²
<h3>Further explanation </h3>A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol of NH₃ = n = 0.074
So the number of molecules :
