Question

effect of temperature on molarity and molality?
plz tell me

Answer 1

Because with increase in temperature, volume of solution also increases. But temperature has no effect on mass. But there is no effect of temperature on molality. For example, with increase in temperature, volume will increase and then molarity will decreases.

hope this helps and mark me as brainliest if it does...

Answer 2

Effect of temperature on molarity:Molarity is affected by the temperature . molarity is the ratio between number of moles of solute to the volume of solution in litres and as on increasing temperature the volume increases and hence with the increase in temperature the molarity of solution decreases .

Effect of temperature on molality:Because with increase in temperature, volume of solution also increases. ... So with change in temperature, molarity also changes. But there is no effect of temperature on molality. For example, with increase in temperature, volume will increase and then molarity will decreases.

Plz mark me as the brainliest.
