Answers
Molarity
1) Molarity is concentration of a substance that is calculated as the number of moles of solute that is dissolved in 1 liter of solution while
2) The symbol for molarity is M,
3) The formula for molarity is moles / liter
4) Molarity is affected by changes in temperature
5) Molarity is affected by changes in pressure
Molality
1)molality is concentration of a substance that is calculated as the number of moles of solute found in 1 kg of solvent.
2)molality is m (sometimes written as –m or m to distinguish it from mass).
3)formula for molality is moles / kg.
4)molality is unaffected by changes in temperature.
5)molality is unaffected by changes in pressure.
Answer:
Molarity and Molality
Molarity and MolalityMolarity (M) is defined as the number of molesof solute per liter of solution.
Molarity and MolalityMolarity (M) is defined as the number of molesof solute per liter of solution.molarity = moles of solute/liters of solution
Molarity and MolalityMolarity (M) is defined as the number of molesof solute per liter of solution.molarity = moles of solute/liters of solutionMolality (m) is defined as the number of molesof solute per kilogram of solvent.

Molarityis a measurement of the moles in the total volume of the solution, whereas molality is a measurement of the moles in relationship to the mass of the solvent.

Molarityis a measurement of the moles in the total volume of the solution, whereas molality is a measurement of the moles in relationship to the mass of the solvent.When water is the solvent and the concentration of the solution is low, these differences can be negligible (d = 1.00 g/mL). However, when the density of the solvent is significantly different than 1 or the concentration of the solution is high, these changes become much more evident.
