A teacher has given a lab student a white chemical sample and asks her to confirm that it contains 7.03 x 1023 formula units of sodium hydroxide(NaOH). Using the balance in the laboratory, what mass of NaOH would the student have to find to verify that her teacher was correct? Round your answer to 3 significant figures.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

we need the questions , i may then you.
