The mass of a single vanadium atom is 8.46×10-23 grams. How many vanadium atoms would there be in a sample of vanadium with a volume of 305 cm3 if the density of vanadium is 6.20 g/cm3? I get confused when I'm given info that is already in scientific form. Do I expand them or do I leave it as it is? And I am not sure what form my answer is supposed to be in.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
