Question

What is the % (m/m) of MgO In a solid sample if 0.500 g of this sample in solution are point using 35.0 mL of EDTA 0.250 M. Consider the reaction below and the table reporting data relative to a rate study at 25 degree C. What is the rate law? The following data were collected during a freezing point depression expirer Mass of Tert-Butyl Alcohol (TBA): 18.356 g Freezing Point of TBA: 22.43 degree C Density of Unknown: 0.790 g/mL Volume of Unknown added to TBA: 1.00 ml Freezing Point of Mixture: 15.17 degree C The unknown used in this experiment is a nonelectrolyte, and the K, for TBA is above, determine the Molar Mass of the Unknown.

Explanation / Answer

3) Answer:C

rate=k[NO]2 [Br2]
