how many grams are in 5.2*10^15 atoms of nickel
1) you need find out what is the molar mass of nickel
2) the mole # of nickel is
5.2*10^15 /(Avogadro's number6.0221415*10^23)
3)# of grams = (mole # )*(molar mass of nickel)
moles Ni = 5.2 x 10^15/6.022 x 10^23 = ??
moles Ni = g/atomic mass. You have moles Ni from above and you can look up the atomic mass NI from the periodic table. That leaves just one unknown, grams.
To determine the number of grams in 5.2 × 10^15 atoms of nickel, you will need to use the molar mass of nickel and Avogadro's number.
1. Find the molar mass of nickel (Ni) from the periodic table. The atomic mass of nickel is approximately 58.6934 grams/mol.
2. Convert the given number of atoms (5.2 × 10^15 atoms) to moles. To do this, divide the number of atoms by Avogadro's number (6.022 × 10^23 atoms/mol).
Number of moles = (5.2 × 10^15 atoms) / (6.022 × 10^23 atoms/mol)
3. Calculate the mass (in grams) by multiplying the number of moles by the molar mass of nickel.
Mass (in grams) = Number of moles × Molar mass
Mass = (Number of moles) × (Molar mass)
Put the values into the equation:
Mass = [(5.2 × 10^15 atoms) / (6.022 × 10^23 atoms/mol)] × (58.6934 grams/mol)
Simplify the equation:
Mass ≈ 4.99 × 10^-8 grams
Therefore, there are approximately 4.99 × 10^-8 grams in 5.2 × 10^15 atoms of nickel.
To find the number of grams in 5.2*10^15 atoms of nickel, you would need to know the molar mass of nickel and use Avogadro's number.
1. First, let's determine the molar mass of nickel. The atomic mass of nickel (Ni) is approximately 58.69 g/mol.
2. Next, we need to find the number of moles in the given number of atoms. To do this, divide the given number of atoms (5.2*10^15) by Avogadro's number, which is approximately 6.022 × 10^23 atoms/mol.
Number of moles of atoms = (Number of atoms) / (Avogadro's number)
Number of moles of nickel = (5.2*10^15 atoms) / (6.022 × 10^23 atoms/mol)
3. Calculate the number of grams using the molar mass and the number of moles of nickel.
Number of grams = (Number of moles) * (Molar mass)
Number of grams = (Number of moles of nickel) * (Molar mass of nickel)
Now, let's plug in the values:
Number of grams = (5.2*10^15 atoms) / (6.022 × 10^23 atoms/mol) * (58.69 g/mol)
Simplifying this expression will give you the amount of grams in 5.2*10^15 atoms of nickel.
