What is the molarity of 2.0 liters of an aqueous solution that contains 0.50 mol of potassium iodide

0.25M

Explanation:

We can apply the following formula to find molarity ,since the Molarity (M) is the number of moles of solute per liter of solution.  

of KI(potassium iodide)

we can substitute the values to find the molarity

So the molarity of 2.0 liters of an aqueous solution that contains 0.50 mol of potassium iodide is 0.25M

Explanation:

Molarity could be defined as the amount of solute (in moles) dissolved in  1 litre of water to give its solution. It can also be referred to as the concentration of the resulting solution.

The molarity is thus calculated as follows;

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
