You can not have 0.4 of an atom (of anything). Thus you question makes no sense.

What is the number of atoms per unit cell for nickel?
According to the U.S. mint the nickels currently in circulation weigh 5.000 grams and contain 25% Ni (the rest is copper). 25% of 5.000g = 1.250 grams of Ni in a nickel coin / molar mass of Ni 58.71 g/mol = 0.02129 moles of Ni times the number of particles for one mole 6.02x10^23 = 1.28x10^22 atoms of Ni in one coin. All together: (0.25 x 5.000g) / (58.71 g per mol) x (6.02x10^23 atoms per mol) = 1.28x10^22 atoms Ni per coin.
How many atoms are in .534 mole of Ni?
3.22e23 atoms
How many total atoms are in one molecule of nickel hydroxide Ni OH2?
Ni(OH)2 1 atom of nickel 2 atoms of oxygen 2 atoms of hydrogen -------------------------------+ total atoms = 5 atoms
How many moles of nickel (Ni) atoms are in 125 g Ni?
There are 58.6934 gram in one mole of Ni atoms, so there are125(g Ni) / 58.6934 (g.mol-1 Ni) = 2.13 moles in 125 gram Ni

How many Hydrogen atoms are in an Alkane with 16 Carbon atoms?
A non cyclic alkane always has a number of hydrogen atoms equal to 2c + 2, where c is the number of carbon atoms. Therefore, hexadecane, an alkane with 16 carbon atoms, will have 34 hydrogen atoms.

How many atoms are in 26.4 g of Ni?
Nickel is 58.7g/mol, so 26.4/58.7=0.45mol, and that times 6.02x1023 (Avogadro's number) gives you 2.71x1023 atoms of nickel.
What is the mass in grams of 5.97 x 1027 atoms of nitrogen?
500,000 atoms * 1 mole Ni/6.022*1023 atoms * 58.693 grams/1 mole Ni = 4.873*10-17 grams Therefore, the mass of 500,000 atoms of nickel is about 4.87*10-17 grams
What is the equivalent to the IRS number in the UK?
The UK equivalent is probably a National Insurance (NI) number. A unique NI number is allocated to every UK individual from the day they leave school - and it is theirs for life. It is used by tax and other government agencies to identify an individual person. A UK NI number consists of two letters, three two-digit numbers and a final letter. An NI number is usually written in the the format... AB 12 34 56 C
