Sodium hydroxide is extremely soluble in water. At a certain temperature, a saturated solution contains 567 g of NaOH(s) per liter of solution. Calculate the molarity of this saturated NaOH(aq) solution

14.2M

Explanation:

Amount= Concentration × Volume

But volume is 1 litre as stated in the question

And amount = mass/ molar mass

Molar mass of NaOH= 23+16+1=40gmol-1

Amount of NaOH= 567/40=14.2moles

But concentration= amount/volume

Hence molarity= 14.2/1 = 14.2M

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:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
