MOLAR MASS

MOLAR MASSAnita Yusrina Kulsum140210140039OutlineIntroductionMethodologyResultConclusionIntroductionGoal of The ExperimentDetermine the molar mass of nonvolatil and nonelectrolite solute through observation of the freezing point difference between solvent and solution.

Methodology

Ice Bath PreparationsBeaker 400ml was prepared

Ice and salt were filled into beaker

The instrument was combined as Figure5Freezing Point of Water (Solvent)

Reaction tube was weighed in a beaker

10 grams of water was added in a reaction tube

The reaction tube was placed in an ice bath

The instrument was combined again as Figure

The temperature was recorded every time interval (15 second)The temperature was constant at the freezing point

Freezing Point of Unknown Solute

The temperature was recorded every time interval (15 second) until constant

The reactiontube was placed back into ice bath

0,1-0,3 gram of solute was added quantitatively into the water in a reaction tubeReaction tube was taken and dried the outer of reaction tube

ResultConclusionThank You
