Which one has a greater concentration, 1 molar NaOH or 1 molal NaOH aqueous solution?
for the answer Explain Why!
for the answer Explain Why!
Symbolipoint is right in general, but wrong in this particular case Besides, looks to me like in practice it always works the same.
Molarity (M) is a measure of the concentration of a solution in terms of the number of moles of solute per liter of solution. Molality (m) is a measure of the concentration of a solution in terms of the number of moles of solute per kilogram of solvent. This means that molarity takes into account the volume of the solution, while molality takes into account the mass of the solvent.
This is because molarity is a measure of concentration in terms of the total volume of the solution, while molality is a measure of concentration in terms of the mass of the solvent. Since the volume of a solution can change with temperature and pressure, molarity can vary. However, the mass of the solvent remains constant, making molality a more accurate measure of concentration.
To calculate molarity, divide the number of moles of solute by the volume of the solution in liters. To calculate molality, divide the number of moles of solute by the mass of the solvent in kilograms.
Yes, the concentration of a solution can affect its properties such as density, boiling point, and freezing point. This is because the concentration of a solution affects the number of particles present, which can impact the physical and chemical properties of the solution.
The concentration of a solution is typically expressed in units of molarity (M) or molality (m). Other common units include percent by mass, percent by volume, and parts per million (ppm).
