How many molecules are contained in 5.00 microliters of methanol (CH4O)? The density of methanol is 0.792 g/mL. Use these atomic masses: C = 12.011 amu; H = 1.008 amu; O = 15.999 amu. Input your result in scientific notation using the format with the lower case e representing the x10. For example, in this format the number 1.234x109 would be expressed as 1.234e9. The number 1.234x10-9 would be expressed as 1.234e-9
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.
