A manufacturer of paint claims that a gallon (3.78 L) of latex paint can cover 365 ft2 of the surface of a wall in a single coating. The paint manufacturer also claims that one single coating of an entire wall will be 3.40 mm thick.  Is this a case of false advertising? Yes or No? Elaborate your answer by providing a calculation (handwritten, upload a pdf). You may use the following conversions: 12 in = 1 ft, 2.54 cm = 1 in

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
