Question

Ivanna add 0.012-mL of a 30.55-M solution of EDTA to her analyte. How man moles of
EDTA did she add to her flask?

Answer 1

Answer:

Number of moles of EDTA added 36.66 × 10⁻⁵  mol.

Explanation:

Given data:

Volume of solution = 0.012 mL

Molarity of solution = 30.55 mole/ L

Number of moles =?

First of all we will convert the given solution in liter.

1 L = 1000 mL

0.012/1000 = 1.2 × 10⁻⁵ L

Formula:

Molarity = number of moles / volume of solution

Number of moles = molarity × volume of solution

Number of moles = 30.55 mol/L ×  1.2 × 10⁻⁵ L

Number of moles = 36.66 × 10⁻⁵  mol
