The concentration of a substance is the quantity of solute present in a given quantity of solution.
I looked it up. The amplitude of a wave is a measure of the displacement of the wave from its resting position.
Answer : The correct option is, forms of the same element that differ in the number of neutrons in each atom
Explanation :
Isotopes : It is defined as the forms of same element that have the same number of protons and electrons but differ in the number of neutrons.
For example : Carbon-12, carbon-13 and carbon-14 is an isotopes due to the same number of protons and electrons and different number of neutrons.
Carbon-12
Atomic number = 6
Atomic mass = 12
Atomic number = Number of protons = Number of electrons = 6
Number of neutrons = Atomic mass - Atomic number = 12 - 6 = 6
Carbon-13
Atomic number = 6
Atomic mass = 13
Atomic number = Number of protons = Number of electrons = 6
Number of neutrons = Atomic mass - Atomic number = 13 - 6 = 7
Carbon-14
Atomic number = 6
Atomic mass = 14
Atomic number = Number of protons = Number of electrons = 6
Number of neutrons = Atomic mass - Atomic number = 14 - 6 = 8
Answer:
q= 110.5 ke
Explanation:
Dipole moment is the product of the separation of the ends of a dipole and the magnitude of the charges.
μ = q * d
μ= Dipole moment (1.93 D)
q= partial charge on each pole
d= separation between the poles(109 pm).
e= electronic charge ( 1.60217662 × 10⁻¹⁹ coulombs)
So,
q= 
coulombs
q = 
e
q = 1.105 * 10⁵ e
q= 110.5 ke
