If 0.290g of fas is dissolved in 10ml of di water and is titrated to equivalence with 12.23ml kmno4, the molarity of kmno4 is calculated to be: mno4−(aq) + 5 fe2+(aq) + 8 h+(aq) → mn2+(aq) + 5 fe3+(aq) + 4 h2o(l)

Molarity of is 0.121 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,

n= moles of solute

= volume of solution  = 10 ml

According to the neutralization law:

where,

= molarity of solution = 0.074 M

= volume of solution = 10 ml

= molarity of solution = ?

= volume of solution = 12.23 ml

= valency of = 2

= valency of = 1

Therefore, the molarity of is 0.121 M

c. orbital shape i hope this is correct
