What would you need to do to calculate the molality of 10 g of NaCI in 2 kg of water?

To calculate the molality of 10 g of NaCl in 2 kg of water, you first need to determine the number of moles of NaCl. This is done by dividing the mass of NaCl (10 g) by its molar mass (approximately 58.44 g/mol). Next, you divide the number of moles of NaCl by the mass of the solvent (water) in kilograms (2 kg) to find the molality. The formula for molality is: molality (m) = moles of solute / kg of solvent.
