Is aluminum atomic weight rounded to 26 or 27?
The gram atomic mass of aluminum, which is defined as the mass of Avogadro's Number of atoms of the element, is 26.9815. To the justified number of significant digits, this is the same as the gram atomic mass. Therefore, the mass stated in the question contains Avogadro's Number of atoms: to the justified number of significant digits, 6.02 X 1023.
What mass of gold contains the same number of atoms as 9.00g of Aluminum?
66
Why is one mole of aluminum larger than one mole of copper?
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
What is the formula mass of a molecule of aluminum chloride if the mass number of aluminum is 27 and chlorine is 35?
Aluminium's (Al) molar mass is = 27 Chloride (Cl3 ) molar mass is = 106.5 ( since its 35.5 * 3) You add those both up and you get = 133.5
Aluminum will react with bromine to form aluminum bromide Al2Br6 What mass of bromine g is needed to form 1.42 mol of Al2Br6?
The gram formula unit or molar mass for aluminum bromide is 533.38.* Therefore, 1.42 moles has a mass of 757.4 grams. The mass of 6 moles of bromine atoms is 479.42. Therefore, the mass fraction of bromine in aluminum bromide is 479.42/757.4 or 0.633, and the mass in grams of bromine required to form 1.42 moles of aluminum bromide is 0.633 X 757.4 or 479 grams, to the justified number of significant digits (limited by the precision given for the number of moles.) ___________________ *This is equal to the sum of (2 times the gram atomic mass of aluminum) and (6 times the gram atomic mass of bromine).
What is the atomic mass of aluminum?
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
What is th mass number of aluminum?
Alluminium is a metal element. Atomic mass of it is 27.
How can you find the number of neutrons that are in the nucleus of an atom?
Aluminum is 13 because that is the atomic number (the number of protons). The atomic mass number is the number of protons and neutrons in an atom. In this, you just subtract the number of protons from the mass number. If Aluminum (Al), #13, has a mass number of 27, then it has 14 neutrons. Pretty simple.

What is the atomic number for Aliminium?
The atomic number for aluminum (Al) is 13, and it has an atomic mass of 27.0
How many neutrons are in the nucleus of the isotopes of aluminum-25?
The atomic number of aluminum is 13, therefore there will be 13 protons.The number of neutrons equals the mass number minus the atomic number. For aluminum-25, that will be 25 - 13 = 12 neutrons.There will be 13 electrons in the neutral atom of aluminum, regardless of which isotope we are considering.
What mass of gold contains the same number of atoms as 9.00g of Aluminum?
66
What element has a 27 atomic mass?
The only element with a radioactively stable isotope with a mass number of 27 is aluminum.
What is the number of Aluminum?
The atomic number for aluminum (aluminium, symbol Al) is 13. This is the number of protons, also known as the "element number." Atomic Mass/weight is 26.981 (most aluminum is 27Al) The atomic weight of Al is 26.981539 amu, and the molar mass 26.981539 grams per mole. (see also the related link below)
An aluminum isotope consists of 13 protons 13 electrons and 14 neutrons It's mass number is what?
Mass number = proton number + neutron number SO, Mass number(Aluminium) = 13+ 14 =27
How would you determine the number of moles of aluminum in 96.7 grams of aluminum?
Number of moles = mass of the sample/atomic weight of Al = 96,7/26,987 = 3,58
What is the atomic number and atomic mass number for aluminum?
The numbers of protons and electrons in any neutral atom are the same as the atomic number, 13 for aluminum. The number of neutrons varies by isotope and can be found by subtracting the atomic number from the atomic mass number. One isotope is Al-27, in which there are 14 neutrons.
