Explanation:
they are located in the neucleus
The value of of is 1.7× .
So, option C is correct one.
Calculation,
Number of moles of = mass/molar mass = 0.45/278.1 = 1.618× moles
Concentration of and ion
Molarity of = Number of moles of solute /volume in lit
Molarity of = 1.618× moles /0.1 lit = 0.0162 M
→ + 2
For certain amount of , twice this amount of ion formed.
The concentration of ion formed = 2× 0.0162 M = 0.0324 M
Now,
of = [ ] = 0.0162 × = 1.7× .

Explanation:
a man out of chronium 8 = 24.6 grams
mass of oxygen = 11.8 grams
mass of oxygen = 1.2 grams
total mass =24.6 + 11.8 + 1.2
=37.6
percent composition by mass of chromium
= 24.6/37.6 = 0.654
The answer fam is......... False
