Answer:

0.18 moles EDTA

Step-by-step explanation:

To find the amount of moles, you need to

(1) convert the volume from mL to L ( 1,000 mL = 1 L)

(2) solve for moles (Molarity = moles / volume)

The answer should have 2 sig figs like the least accurate given value.

91 mL EDTA 1 L
---------------------- x ---------------------- = 0.091 L
1,000 mL

Molarity = moles / volume (L) <----- Molarity ratio

1.94 M = moles / 0.091 L <----- Insert values

0.176 = moles <----- Multiply both sides by 0.091 L

0.18 = moles <----- Correct sig figs
