<u>Answer:</u> The molar solubility of MX is
<u>Explanation:</u>
We are given:
The chemical equation for the ionization of MX follows:
S S
The expression of for above equation is:
......(1)
The chemical equation for the ionization of follows:
0.25M 0.5M 0.25M
Total concentration of cation from both the equation is:
As, , so S is also very very less than 1 and can be easily neglected.
So,
Putting values in equation 1, we get:
Hence, the molar solubility of MX is
Answer:
C
Explanation: thats what i got
Total mass, in grams, of all the particles in one mole of the substance
Explanation:
- Molar mass is defined as the ratio of the given mass of the substance to the amount of the given substance in moles.
The formula is, Molar mass =
- By definition, these are mass in grams of all the particles in one mole of the substance. The unit of molar mass is g/ mol
- The molar mass of the element is what we see in the periodic table. The periodic table is constructed according to the atomic number of each elements and there represented the atomic mass, which is the molar mass of the elements.
Given
Mass number of isotope = 63
Number of neutrons = 33
So number of protons = 63 - 33 = 30
Hence atomic number of metal = 30
thus metal is = zinc
now as it is forming cation with 28 electrons it means it has lost two electrons so it must have a dipositive charge
the symbol of metal ion will be
Zn^+2
