Answer:
The answer is 1.29473 x 10^24
Explanation:
Intensive properties are the properties which values doesnt change with the amount of mass or material that you have, example density, melting point boiling point, molecular mass
Extensive are properties that depends of how much mass or material you have. Example: mass, number of moles, volume, pressure, number of students, population,
mass, volume, quantity (there is only one of each), color, reflect light, temperature, energy
Answer:
the molecules of each substance attract each other through dispersion (London) intermolecular force.whether a substance is solid, liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions.
thank you.
Explanation:
Number of moles(n)=Number of atoms(N)/Avogadro's constant.
Avogadro's constant=6.02×10²³
so we have
n=9.05×10²³/6.02×10²³
n=1.0503moles.
n=mass/molar mass
1.0503=mass/28
mass=1.0503×28
mass=29.4084g
It's K since K and Na are in the same family
