Molarity of .100 mole of urea (CH4N2O) in 250.0 mL of solution
M= moles/L soln.
You have moles (0.1) and you have liters (0.250L). What more do you want?
To calculate the molarity (M) of a solution, you need to know the amount of solute (in moles) and the volume of the solution (in liters).
Given:
Amount of solute = 0.100 moles
Volume of solution = 250.0 mL = 0.250 L
To calculate molarity, divide the amount of solute by the volume of the solution:
Molarity (M) = Amount of solute (moles) / Volume of solution (L)
Plugging in the values:
Molarity (M) = 0.100 moles / 0.250 L
Now, let's calculate this:
Molarity (M) = 0.40 M
Therefore, the molarity of 0.100 moles of urea (CH4N2O) in 250.0 mL of solution is 0.40 M.
