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?
There are 4.53 x 10^23 atoms in 0.75 moles of neptunium. This is because one mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23.
How many total atoms are in one molecule of nickel hydroxide Ni OH2?
One molecule of nickel hydroxide (Ni(OH)2) contains 5 atoms: one nickel atom, two oxygen atoms, and two hydrogen 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.
What is the empirical formula of a compound that contains 10.52g Ni 4.38g C and 5.10gN?
The molar masses of Ni, C, and N are approximately 58.69 g/mol, 12.01 g/mol, and 14.01 g/mol, respectively. In this case, we first convert the given masses to moles: Ni (0.179 mol), C (0.364 mol), and N (0.364 mol). Then, we divide each by the smallest number of moles to find the mole ratio. This simplifies to NiC2N2, making the empirical formula Ni(CN)2.
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

There are 4.53 x 10^23 atoms in 0.75 moles of neptunium. This is because one mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23.
How many total atoms are in one molecule of nickel hydroxide Ni OH2?
One molecule of nickel hydroxide (Ni(OH)2) contains 5 atoms: one nickel atom, two oxygen atoms, and two hydrogen atoms.
What is the number of atoms per unit cell for nickel?
The number of atoms per unit cell for nickel is 1. Nickel crystallizes in a face-centered cubic (FCC) structure, with one nickel atom located at each corner of the unit cell and one nickel atom at the center of each face of the unit cell. This gives a total of 4 nickel atoms per unit cell.

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.
