Document Summary
C18h32o16 a carbohydrate, why: h20 was taken out of the molecule dehydration synthesis. Atomic mass- # of protons and neutrons: theyre important because they tell us how atoms bond with each other. The polarity of the molecule, and soluabliity: whether it goes into a solution or not, it"s really important for biology, ex. Oxygen has an atomic number of 8. Therefore it has 8 protons and 8 electrons: oxygen needs to gain 2 electrons. They try for the fewest number: valence electrons are the electrons that are currently on the ring, electronegativity is the attraction an atom has for an electron, shells: 2,8,8,8. Molecular weight: protons + neutrons= atomic mass, find molecular weight of c6h12o6, if one molecule has the mass of 180 daltons. 1 mole of glucose molecules has the mass of 180 grams: concentration- the number of molecules per value (moles) or moles per liter (molarity, 0. 25 mol glucose solution= 45 grams, 0. 5 liters= 90 grams.
