sciencespot.net › Media › AtomicBasicsChemistry of Matter - Science Spot NOTE: The number protons and electrons is equal to the atomic number. To find neutrons, subtract the number of protons from the atomic mass. To find the atomic mass, add the number of protons and neutrons. O Oxygen 15.999 ATOMIC NUMBER SYMBOL NAME ATOMIC MASS wou.edu › chemistry › coursesChapter 6 – Quantities in Chemical Reactions – Chemistry For a larger molecule, like glucose (C 6 H 12 O 6), that has multiple atoms of the same type, simply multiply the atomic mass of each atom by the number of atoms present, and then add up all the atomic masses to get the final molecular mass. The mole concept can be extended to masses of formula units and molecules as well. byjus.com › maths › factors-of-135Factors of 135 | How to Find the Prime Factors of 135 by the ... The numbers that divide the given number evenly without leaving any remainder are called the factors of a number. Thus, the factors of 135 are the numbers that divide 135 completely and leave a remainder 0. As 135 is a composite number, it has many factors other than 1 and 135. Hence, the factors of 135 are 1, 3, 5, 9, 15, 27, 45 and 135.
