0.862 mol of KCl is dissolved in 2000 mL of water. What is the concentration of this solution? __ m (answer with 1 significant figure) Blank 1: square

To find the concentration of the solution in molality (m), we need to use the formula:<br /><br />molality (m) = moles of solute / kilograms of solvent<br /><br />Given information:<br />- Moles of KCl: 0.862 mol<br />- Volume of water: 2000 mL (or 2 L)<br /><br />Step 1: Calculate the mass of water in kilograms.<br />Density of water = 1 g/mL<br />Mass of water = 2000 mL × 1 g/mL = 2000 g<br />Kilograms of water = 2000 g / 1000 g/kg = 2 kg<br /><br />Step 2: Calculate the molality of the solution.<br />molality (m) = 0.862 mol / 2 kg = 0.431 m<br /><br />Rounding the answer to 1 significant figure, the concentration of the solution is 0.4 m.<br /><br />Blank 1: 0.4
