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 atoms are in 0.75 moles of neptunium?
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
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
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.
What is the empirical formula of a compound that contains 10.52g Ni 4.38g C and 5.10gN?
As usual, go for the moles. 10.42 grams Ni (1 mole Ni/58.69 grams) = 0.1775 moles Ni 4.38 grams C ( 1 mole C/12.01 grams) = 0.36469 moles C 5.10 grams N (1 mole N/14.01 grams) = 0.36403 mole N Now, the least mole value represents the whole number 1 and it divides the other numbers to get the whole numbers for the subscripts. 0.36469 mole C/0.1775 mole Ni = 2.05, call it 2 0.36403 mole N/0.1775 mole Ni = 2.05, also called 2 As you gave the species order ( though I am not sure of this ) NiC2N2
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
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 atoms are in 0.75 moles of neptunium?
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
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

What is the number of Ni atoms in 3.4 atoms of Ni?
You can not have 0.4 of an atom (of anything). Thus you question makes no sense.
How many atoms of oxygen are represented in this expression3Ni(OH)2?
3 Ni(OH)2 contain six oxygen atoms.
How many moles is 176.1 grams of nickel?
1 mole of nickel is 58.69 grams. 176.1 g Ni * (1 mol Ni/58.69 g Ni) = 3.0005 mol Ni Therefore, 176.1 grams of nickel is equal to 3 moles of nickel.
What mass in milligrams does 2.63 moles of nickel have?
1 mole Ni = 58.6934g 1g = 1000mg 2.63mol Ni x 58.6934g Ni/mol = 154g Ni 154g Ni x 1000mg/g = 154000mg Ni
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.
How many oxygen atoms are present in one molecule of nickel hydroxide?
Nickel Hydroxide is Ni(OH)2. So 1 molecule of Nickel Hydroxide contains 2 oxygen atoms.
