Explanation:
The ionic strength of a solution, I, is defined as
I=1/2 Σ m_i z_i^2
Where m_i is the concentration of the ion, and z_i is the charge of the ion.
For 1 M NaCl solution, Ionic strength I = ½ (1*12 + 1*12) = 1.00;
For, 1 M (NH4)2SO4, concentration of [NH4] = 2 M and [SO4] = 1 M;
I = ½ (2*12 + 1*22) = 3.00;
so ionic strength of 1 M (NH4)2SO4 is different, therefore it is a serious error.
Answer :
A = In
B = 27
C = 73
D = 49
E = 56
F = 54
G = 66
H = 108
I = 32
Explanation :
Atomic number is defined as the number of protons or number of electrons.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and number of neutrons.
Number of neutrons = Mass number - Number of protons
Number of electrons = Number of protons - charge
Element Number of Number of Number of Atomic
