What is the mass number fr gold?
Gold (Au) has a mass of 196.96655 amu. Actually the mass number if gold is dependent on the number of neutrons in the mix. Gold has 79 protons and the isotope that gold is at the time will determine the mass number. So, mass number = # of protons + # of neutrons...this is for any element.
What is the mass number of gold?
The mass number of gold is 197. This number represents the total number of protons and neutrons in the nucleus of a gold atom.
What is gold mass number?
The only stable, and only naturally-occurring isotope of gold has mass number of 197. This is the number of protons and neutrons in each nucleus. Gold's atomic number is 79. This is the number of protons found in each gold atom. This determines its place in the periodic table, and its chemical properties: it is the defining property of gold. A nucleus with a different number of neutrons and the same 79 protons would be a different isotope with a different mass number; a nucleus with a different number of protons would not be gold, but some other element.
An atom of gold with 79 protons 79 electrons and 118 neutrons. What's the mass number?
The mass number is the sum of protons and neutrons in the nucleus of an atom. In this case, an atom of gold with 79 protons and 118 neutrons would have a mass number of 197 (79 protons + 118 neutrons = 197 mass number).
How many atoms of gold are in the bar?
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.

What is the mass number ofgold?
Gold is a metal element. Atomic mass of it is 197.
How many moles of gold are in 3.60x10-5g of gold?
To find the number of moles of gold, first calculate the molar mass of gold, which is 197 g/mol. Then, divide the given mass of gold by the molar mass to find the number of moles. In this case, 3.60x10-5g ÷ 197 g/mol ≈ 1.83x10-7 moles of gold.
What is the atomic mass number of element d?
The atomic mass number of an element is the total number of protons and neutrons in its nucleus. It is denoted by the symbol A. If you provide the symbol or name of element d, I can tell you its atomic mass number.
