The concentration of iodine is found to be 75 x 103 molL How

The concentration of iodine is found to be 7.5 x 10^-3 mol/L. How many moles of iodide are present in the original 10.00 mL solution?

Solution

7.5x10^-3mol per 1000 mL (liter)

X moles? in 10 mL

X=7.5x10^-3x 10/1000

X= 7.5X10^-5mol

so no of moles of iodide =2 x7.5x10^-5 mol
