What is the molarity of a 200. mL solution in which 0.20 mole of sodium bromide is dissolved?
drbob222 are you as useless as a person as your answer is
he is saying M =Moles divided by liters
(I think)
To calculate the molarity of a solution, you need to know the amount of solute (in moles) and the volume of the solution (in liters).
In this case, you are given the amount of solute (0.20 moles of sodium bromide) and the volume of the solution (200 mL or 0.200 liters).
The formula to calculate molarity is:
Molarity (M) = moles of solute / volume of solution (in liters)
So, to find the molarity, divide the moles of solute by the volume of the solution:
Molarity (M) = 0.20 moles / 0.200 liters
Calculating this expression will give you the molarity of the solution.
