The Mole

Unlock the mystery of the mole in chemistry! Understand Avogadro's number and master molar mass calculations.

Understanding the MOLE This video with help you with understanding why we use the concept of the MOLE. Take some notes on a google doc or in a spiral. While watching the video, use the word bank to fill in the blanks. Type your answers in the spaces. A mole is a concept used in chemistry to count molecules,atomsand just about anything extremely small. In 1811, someone had an idea that if you had equal volumes of gas at the same temperature and same pressure, they would have the same number of molecules. If you pour 18.01 grams of water into a glass, you will have 6.02x10^23molecules of water. Avogadro'snumber, 6.02x10^23, is also referred to as a mole. If you had a mole of donuts, it would cover the whole earth to a depth of 18kilometers. Chemists use the mole that same way you would use poundsto buy food at the deli. # of Moles Molar Mass Element 1 12.011 Carbon 1 26.982 Aluminum 1 6.941 Lithium 1 4.003 Helium 1 15.999 Oxygen 1 1.008 Hydrogen Calculating Molar Mass Watch the video below about calculating molar mass and then practice the calculations below.
