TOPIC WILL BE "Formula Mass for Covalent Substances"Re-explain Formula Mass for Covalent Substances to the class as if you were teaching it to them in a way they can understand it. So, it needs to be your own delivery style and in your own words--don't just re-state what is already written in the text with the big words given there. As we learn, we all make different associations with the new material with previous knowledge we have, and we often form visual images or learning devices in our heads to help us understand concepts being presented. So, share those. Help us understand how YOU understand and came to understand the material, and maybe hearing the concept explained in a different way will help someone else understand it a little better. If not, it will most definitely make you think about the concept at a level of true understanding, so that you will not just have a cursory understanding of the material/concept, but rather an operational understanding on which you can build your future learning.

Answer

Formula Mass for Covalent SubstancesIn a covalently bonded compound, formula mass is also known as molecular mass (p, 2). It is obtained by summing up all the atomic masses of each atom present in the compound. It is expressed in atomic mass units (amu) (p, 2). Consider a simple molecule such as ethanol. To obtain its formula mass, one must first write down its chemical formula correctly; C2H5OH (p, 3). From this, one can see that a molecule of ethanol is composed of two carbon atoms, six hydrogen atoms, and one oxygen atom. Therefore, to obtain the molecular mass of ethanol:AtomnumberAverage Atomic mass in amuTotal mass in amuC2x12.0124.02H5x1.005.00O1x16.0016.00Formula mass=45.02Consider a complex structure molecule such as 4- Isopropyl aniline.Write down its chemical formula: C9H13NNine...
