Question

6. Hans Gruber reports that he collected a sample of ethanol from his distillation with a density of 0.798 g/mL and a purity of 97.2%. Why is this data certainly wrong?

A mass of 4.82 g was recorded for a 5 mL sample of ethanol at 25 degree C. Calculate the specific gravity in g/mL Answer: Check Jamie reports their solution density as 1.25 g/mL. This value is Choose... Choose... Marley reports their solution density as 0.72 g/mL. This value is Choose.. Taylor reports their solution density as 0.85 g/mL. this value is Choose... Choose... Check Hans Gruber reports that he collected a sample of ethanol fron Answer: too high to be reasonable is higher than the density of pure water too low to be reasonable is lower than the density of pure ethanol reasonable is between the densities of pure water and pure ethanol.

Explanation / Answer

4) 0.964 GR/ML   ( 4.82/5)

DENSITY OF WATER IS TAKEN AS 1GR/ML

[ACTUALLY SPECIFI GRAVITY OF MATERIAL = DENSITY OF THAT MATERIAL/DENSITY OF WATER.]

5) is higher than the density of pure water.

5) is lower than density of pure ethanol.

5) is too high to be reasonable for ethanol.

6) because this density is higher than the density of pure ethanol, so there must be still some impurity present (impurity like moisture)
