What is the atomic number of pyrite?
pyrite is a mineral consisting of 2 elements, so it doesn't have an atomic number. pyrite consists of iron and sulfur; FeS2 (Fe=1 Iron atom & S2= 2 Sulfur atom; these three atoms make a pyrite molecule). i this helped
How many neutrons would be present in the nucleus of an atom of iron-56?
I am understanding you to mean an iron-57 ion with a charge of 3+.The atomic number of Fe is 26, which means that all Fe atoms or ions have 26 protons in their nuclei.In a neutral Fe atom, the number of electrons would be the same as the number of protons, which is 26. The charge on the Fe ion is 3+, which means the Fe atom has given up 3 electrons. So the number of electrons in an Fe3+ ion is 26-3, which is 23.The mass number of iron-57 = 57. The mass number is the sum of protons and neutrons in the atomic nuclei of iron-57 atoms. We know the number of protons is 26. The number of neutrons = mass number - the number of protons, which is 57-26 = 31 neutrons.To summarize:The number of protons in all Fe atoms is 26.The number of electrons in an any Fe3+ ion is 23.The number of neutrons in an iron-57 atom is 31.
How many atoms are there in 55.8 grams of Fe?
Avogadros number (approximately). The atomic weight of iron is 55.845. Avogadros number , the number of atoms in a mole of an element, or the number of molecules in a mole of a compound is 6.023 X 1023
How many grams is a sample containing 2.71 x 1024 atoms of iron?
Amount of Fe = (2.71x1024)/(6.02x1023) = 4.50mol The atomic mass of Fe is 55.8 Mass of Fe = 4.50 x 55.8 = 251g
