How many atoms are in 70.620 g of rhenium?
To determine the number of atoms in a given mass of an element, you need to know the molar mass of that element. The molar mass of rhenium (Re) is 186.207 g/mol. To find the number of atoms in 70.620 g of rhenium, divide the given mass by the molar mass, and then multiply by Avogadro's number (6.022 x 10^23). This gives approximately 1.590 x 10^23 atoms of rhenium.
The atomic number of Re is 75 The atomic mass of one of its isotopes is 186 How many neutrons are in an atom of this isotope?
The atomic mass minus the atomic number equals the number of neutrons. Thus in the case above the number of neutrons would calculate out to be 11. HOWEVER PLEASE NOTE Rhenium (Re) does not have an atomic mass of 86, it has two isotopes one of atomic mass 185 and another of atomic mass 187. Thus the real number of neutrons is 110 or 112.
What element has 75 protons in period 6 of the periodic table?
At-Astatine Because it is the 85th element of the periodic table. That means that it has 85 protons and 85 electrons
In period 6 what element has 75 protons?
The element with 75 protons in period 6 is Rhenium (Re), which has an atomic number of 75.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
Is the atomic weight of the rhenium?
The relative atomic mass is 186.207
Atomic number 75?
Arsenic (As) has 33 protons, giving it an atomic number of 33 and, in it's most common isotope, it has 42 neutrons. Atomic mass is equal to (number of protons + number of neutrons). 33 + 42 = 75.
What is the atomic number of rhenium?
Rhenium, with the chemical symbol Re, is the chemical element with the atomic number 75.
What is made of rhenium?
Rhenium is an chemical element with atomic number 75. It is frequently used with tungsten because it adds favorable properties. It is also used for filaments in mass spectrographs.
