Skill 1.3 Identify various approaches to conducting scientific investigations and their applications. 

The design of chemical experiments must include every step to obtain the desired data. In other words, the design must be complete and it must include all required controls. 

Familiarity with individual experiments and equipment will help you evaluate if anything is missing from the design. For data requiring a difference between two values, the experiment must determine both values. For data utilizing the ideal gas law, the experiment must determine three values of P, V, n, or Tin order to determine the fourth or one value and a ratio of the other two in order to determine the fourth. 

Example In a mercury manometer, the level of mercury in contact with a reaction vessel is 70.0 mm lower than the level exposed to the atmosphere. 

What additional information is required to determine the pressure in the vessel in kPa
