To find the molarity of the solution, we need to divide the number of moles of KCl by the volume of water in liters.<br /><br />Given:<br />Number of moles of KCl = 0.046 moles<br />Volume of water = 4.0 liters<br /><br />Molarity = Number of moles / Volume of water<br />Molarity = 0.046 moles / 4.0 liters<br />Molarity = 0.0115 moles/L<br /><br />Rounding to 2 significant figures, the molarity of the solution is 0.011 moles/L.
