What is the total number of atoms contained in 2.00 moles of nickel?

  The number of  atoms  that are contained in  2.00 moles  nickel  is calculated  by use of Avogadro  law  constant

that is  1 mole  =  6.02  x10^23   atoms

what  about 2 moles = ?  atoms

= ( 2moles /1mole)  x 6.02 x10^23  atoms = 1.204  x10^24  atoms   of nickel  are there in  2 moles  of nickel

The total number of atoms contained in 2.00 moles of nickel is 1.204 × 10²⁴ atoms

HOW TO CALCULATE NUMBER OF ATOMS:

The number of atoms in an element can be calculated by multiplying the number of moles by Avogadro's number. That is;no. of atoms = no. of moles × 6.02 × 10²³According to this question, there are 2 moles of nickel (Ni). The number of atoms can be calculated as follows:no. of atoms = 2 × 6.02 × 10²³no. of atoms = 12.04 × 10²³no. of atoms = 1.204 × 10²⁴ atomsTherefore, the total number of atoms contained in 2.00 moles of nickel is 1.204 × 10²⁴ atoms.
