Answer:
Van't Hoff factor is 2, in the sodium chloride
Explanation:
Let's raise the dissociations
- Ca₃(PO₄)₂ → 3Ca²⁺ + 2PO₄⁻³
We have 5 moles of ions
We have 4 moles of ions
We have 3 moles of ions
We have 2 moles of ions
The formula to determine the average atomic mass is:
Average atomic mass = + + ........ -(1)
The atomic mass of first isotope of magnesium = 24 u (given)
The natural abundance of first isotope = 78.70 % (given)
The atomic mass of second isotope of magnesium = 25 u (given)
The natural abundance of first isotope = 10.13 % (given)
The atomic mass of third isotope of magnesium = 26 u (given)
The natural abundance of first isotope = 11.17 % (given)
Substituting the values in formula (1):
atomic weight =
atomic weight =
Hence, the atomic weight of naturally occurring isotopic mixture is .
