For example, 1 gram-atomic weight of atomic oxygen, O (atomic weight approximately 16), is 16 grams. See gram-molecular weightgram-molecular weight,amount of a molecular substance whose weight, in grams, is numerically equal to the molecular weight of that substance. For example, one gram-...
The average atomic mass of oxygen is 15.999 AMU. This value rounds to 16, which indicates that oxygen-16 is the most abundant isotope of oxygen...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer your ...
The elements defined the atomic mass unit as '1/16th of the atomic weight of oxygen'. Apart from the fact that the term mass should have been used instead of weight, this definition does not specify which oxygen isotope, and implies the average mass of an oxygen atom in the mixture of ...
Some of the values that he reported in that first table were: nitrogen: 4.2; carbon: 4.3; oxygen: 5.5; phosphorus: 7.2; and sulfur: 14.4. Words to Know Atomic mass unit (amu): A unit used to express the mass of an atom equal to exactly one-twelfth the mass of a carbon-12 atom...
What is the atomic mass/weight of an atom that has 24 protons, 26 neutrons, and 24 electrons? How many elements have an atomic number of 42? Atomic mass represents What is the atomic number for uranium-235? What is the atomic number of oxygen-16?
∴ Gram molecular mass of oxygen = 32 g Learn how to calculate the number of mole and equivalent weight. Solved Example For You Q: The specific heat of a metal of atomic mass 32 is likely to be: 0.25 0.24 0.20 0.15 Solution: Specific heat = 6.4/atomic mass Therefore, Specific Heat =...
