3.00 mL of 0.00200 M Fe3+ is mixed with 4.00 mL of 0.00200 M SCN– and 3.00 mL of H2O? What is the initial concentration of Fe3+ after mixing, but before any reaction takes place?

Answer : The concentration of after mixing is,

Explanation :

First we have to calculate the moles of before mixing.

Now we have to calculate the total volume of solution after mixing.

Volume of solution = (3.00 + 4.00 + 3.00) mL

Volume of solution = 10.00 mL = 0.010 L

Now we have to calculate the concentration of after mixing.

Thus, the concentration of after mixing is,

can you list the answers so i can answer

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
