The atomic mass of aluminium is given to be 27 u. This means that 1 mole of aluminium atoms has a mass of 27 grams. Now, 1 mole of aluminium atoms = 27 g So, 4 moles of aluminium atoms = 27 xx 4 g = 108 g Thus, the mass of 4 mole
The atomic mass of aluminium is {eq}27 {/eq} g/mol. If its diameter is {eq}d {/eq} then its volume is {eq}\pi d^3/6 {/eq}. Now we can substitute...Become a member and unlock all Study Answers Start today. Try it now Create an account...

To find the radius of an aluminium atom nucleus as per Rutherford's deductions, we can follow these steps:Step 1: Understand the Formula According to Rutherford's model, the radius \( R \) of the nucleus can be calculated using
And finally, the premium class of consumer electronics is also ready for a further display revolution: if production is only standardized to such an extent that mass production of even very large panels is possible at reasonable costs, manufacturers of screens for the living room at home should ...
Once doped, electrical contacts are formed on the SOI substrate by means of thermal evaporation of 200 nm of aluminium, followed by a protective layer of 20 nm of nickel and 200 nm of gold (nickel is required to avoid the growth of further insulating intermetallic layers between ...
The Commission on Isotopic Abundances and Atomic Weights (ciaaw.org) also revised the standard atomic weights of fifteen elements based on the 2012 Atomic Mass Evaluation: aluminium (aluminum) to 26.981 5385(7) from 26.981 5386(8), arsenic to 74.921 595(6) from 74.921 60(2), beryllium ...
