The angle of incoming sunlight varies at different places.
The dissociation of butanoic acid in water gives CH3CH2CH2COO^- and H+
This is according to the following equation
CH3CH2CH2COOH + H2O --->CH3CH2CH2COO^- + H^+
Assuming the molar mass of oxygen is 18.01, you only need 16 grams (B) of oxygen because the molar mass of hydrogen is about 1 gram.
16+1+1=18
Answer: Divide the mass of the object by its volume to yield the density of the object. For example, the object density = mass / (Vf – Vi). Compare the measured density to that of pure gold (19.3 g/cc) to determine whether the object is made of pure gold.
