Calculate the mass of ammonia NH3 that contains a million ×1.000106 hydrogen atoms. Be sure your answer has a unit symbol if necessary, and round it to 4 significant digits.

A student performs an experiment to determine the density of a sugar solution. They obtain the following results: 2.02 g/mL, 2.01 g/mL, 2.00 g/mL, 1.99 g/mL. If the actual value for the density of the sugar solution is 1.75 g/mL, which statement below best describes their results? Their results are neither precise nor accurate. Their results are both precise and accurate. Their results are accurate, but not precise. O Their results are precise, but not accurate.
