How do you calculate the number of grams of Al in 286 g of Al2O3 .?
To find the number of grams of Al, first calculate the molar mass of Al2O3 (2Al + 3O). Then, find the molar mass of Al. Divide the molar mass of Al by the molar mass of Al2O3 and multiply by 286 g to get the grams of Al in 286 g of Al2O3.
How may neutrons in Aluminium?
Aluminium has roughly a couple dozen isotopes; but the only one both stable and naturally occurring has 14 neutrons (mass number of 27).
Which element has a mass number of 27?
Aluminium or aluminum (they're the same element, just spelt and pronounced differently depending on where you are from)
How many grams of aluminum are contained in 100.0 g of aluminum chloride?
The gram atomic mass of aluminium is 26.9815, and the gram atomic mass of chlorine is 35.453. The formula shows that there are three chlorine atoms for each aluminium atom in the compound. Therefore, the mass fraction of aluminium in the compound is 26.9815/[26.9815 + 3*(35.453)] or about 0.20235004, and the grams of aluminium present are 20.24, to the justified number of significant digits. _______________________________________ *An exact integer.
What is aluminums symbol?
the symbol is Al and the charge is negative 3.
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
