In 1993 the Minnesota Department of Health set a health risk limit for 1,2-dlbromoethane In groundwater of 4.00 ng/L. Suppose an analytical chemist receives a sample of groundwater with a measured volume of 78.0 mL. Calculate the maximum mass In micrograms of 1,2- dibromoethane which the chemist could measure In this sample and still certify that the groundwater from which it came met Minnesota Department of Health standards. Be sure your answer has the correct number of significant digits.

A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of molybdenum in these samples: Mo 99.91 Mo 95.90 x A ALEKS - Elizabeth Galaz - Learn x mass relative (amu) abundance Mo 0 96.2% Explanation 3.8% Use these measurements to complete the entry for molybdenum in the Periodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass to 3 significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for molybdenum in the Periodic Table we use here on Earth.
