9.49.8 grams of Kl is dissolved in 1.00 kg of solvent. What is the molality?

Answers

Answer:

Molality = 9.498 mol k g − 1

Explanation:

A final way to express the concentration of a solution is by its molality. The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride.

molality = number of moles of solute/ mass of solvent in kg

number of moles of KI = mass of KI / molar mass of KI

number of moles of KI = 9.49.8 g / 1.00 g m o l − 1

number of moles of KI = 9.498 moles

molality = 9.498 moles / 1kg

molality = 9.498 mol k g − 1

O Large towns are less vulnerable, being part of an international market that sees preserved foods traded long-distance, but much of the countryside is dependent on fresh food. O After a poor harvest, prices for all commodities--not just grain-rise dramatically and the poor are unable to make ends meet.
