A general chemistry student performs an experiment in which two liquids are mixed and, as soon as they meet, a white solid forms
in the solution. Which of the following is a quantitative observation that could be derived from the result of this experiment? a. The mass of the solid formed is 0.5 g.
b. The solid formed is white.
c. A volume of 10 mL of each of the liquid components was used in the experiment.
d. The solid forms quickly after the liquids are mixed.
An experimental observation can either be QUANTITATIVE OR QUALITATIVE. A quantitative observation is that which uses numerical representation to describe collected data. Examples are height, volume, mass etc.
According to this question, a student performs an experiment in which two liquids were mixed to result in the formation of a WHITE SOLID in the solution. Based on the options provided, the quantitative observation that could be derived from the result of this experiment is that "The mass of the solid formed is 0.5g".
Note that, the option that states that: volume of 10 mL of each of the liquid components was used in the experiment is also a qualitative observation but it is not derived from the RESULT of the experiment.
