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?

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

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
