Molarity is defined as the number of moles of solute in 1 L of solution
number of moles of NaI - 10.7 g / 150 g/mol = 0.0713 mol
there are 0.0713 mol in 0.250 L
we need to find the number of NaI moles in 1 L
if 0.250 L contains - 0.0713 mol
then 1 L contains - 0.0713 mol / 0.250 L = 0.285 mol/L
molarity is 0.285 M
Can you give a little more info :)

A.) Cesium is the lowest electronegative element......
A substance and a solution have both uniform composition throughout. A substance is a matter that is uniform in composition and can be an element or compound.
