Question

What is the concentration of a 450 mL solution that contains 200 grams of iron (II) chloride?

Answer 1

`"Concentration"` `=` `"Moles of solute"/"Litres of solution"`

Explanation:

`"Moles of solute"` `=` `(200*g)/(126.75*g*mol^-1)` `=` `1.58*mol`

`"Concentration"` `=` `(1.58*mol)/(450xx10^-3*L)` `=` `3.5*mol*L^-1` with respect to `FeCl_2`.
