Final answer:
The density of pure elemental potassium is typically about 0.862 g/cm³. To find the density, the formula D=m/V is used; however, for elemental properties, standard values from references are used rather than carrying out an experiment.
Step-by-step explanation:
To calculate the density of potassium, we need two pieces of information: the mass and the volume of potassium. However, in the context provided, we're not given the volume of the potassium itself, only the mass of a potassium-containing compound (potassium hydroxide) used in a different experiment. Since pure elemental potassium's density is not dependent on an experiment involving a potassium compound in solution, we'll use a standard reference for potassium's density instead.
The density of elemental potassium is typically found to be about 0.862 g/cm³ at room temperature. This information is usually found in a standard periodic table or chemistry reference material. To calculate density, the formula is D = m/V, where D stands for density, m stands for mass, and V stands for volume.
