Calculate the number of aluminium ions present in 0.051 g of aluminium oxide. (Hint: The mass of an ion is the same as that of an atom of the same element. Atomic mass of Al = 27 u)
Calculate the number of aluminium ions in 0.051g of aluminium oxide (Al_(2)O_(3))
What is the mass of 4 moles of aluminium atoms? (Atomic mass of Al = 27 u )
The number of atoms of 0.03 g of aluminium is nearly (Al = 27)
The density of aluminium is 2700 " kg m^(-3) , Aluminium crytallises in face - centred cubic lattic. Calculate the radius of aluminium atom in meters (Atomic mass of Al = 27)
Calculate the number of moles in 69 g of Na. given : Atomic masses : Al=27.0 u, Na=23.0 u
A quantity of aluminium has a mass of 54.0 g . What is the mass of the same number of magnesium atoms ?.
Calculate the number of unit cells in 8.1 g of aluminium if it crystallizes in a face-centred cubic (f.c.c.) structure. (atomic mass of Al=27g mol^(-1) )
Calculate the mass of sodium which contains same number of atoms as are present in 15 g of calcium (at. mass of Ca = 40, Na = 23).
