What is relative relative atomic mass?
The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, the average mass of one atom of chlorine is found by considering 100 atoms of chlorine.
What is relative atomic mass and relative molecular mass?
1. The ratio of the average mass of one molecule of an element or compound to one twelfth of the mass of an atom of carbon-12 is called the relative molecular mass. 2. Relative atomic mass of the atom of an element is defined as the average mass of the atom, as compared to [112]th the mass of one carbon-12 atom.
What is the mass number of a cobalt atom with 27 protons and 30 neutrons?
What is the mass number of a cobalt atom that has 27 protons and 30 neutrons? 27 + 30 = 57.
What is the mass of CO no3 2.6 h2o?
=290.93g/mol.
Why is it called relative atomic mass?
For example – carbon is 12 times heavier than one hydrogen atom. Relative atomic mass is the atomic weight compared to 1/12 the mass of one atom of carbon. Since it is a comparison of atomic weight with 1/12 the mass of an atom of carbon it is termed relative atomic mass.
What is relative atomic mass class 9th?
Relative atomic mass of the atom of an element is defined as the average mass of the atom, as compared to [112]th the mass of one carbon-12 atom.
What is the average atomic mass for cobalt?
Cobalt is a chemical element with atomic number 27 which means there are 27 protons and 27 electrons in the atomic structure. The chemical symbol for Cobalt is Co. Atomic mass of Cobalt is 58.9332 u.
What is the atomic number and mass number of cobalt?
Name: Cobalt: Symbol: Co Atomic Number: 27: Atomic Mass: 8.9332 atomic mass units
Which has a lower atomic mass lead or cobalt?
The isotopes of cobalt range in atomic weight from 50 u (50 Co) to 73 u (73 Co). The primary decay mode for isotopes with atomic mass unit values less than that of the most abundant stable isotope, 59 Co, is electron capture and the primary mode of decay in isotopes with atomic mass greater than 59 atomic mass units is beta decay.
How do you calculate atomic mass?
Note that the relative atomic masses listed on the periodic table are average values for the associated element.
