Question

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

Answer 1

Answer:

Avagadros number states that 1 mol of any substance is made of 6.022 x 10²³ units. These units could be atoms making up elements or molecules making up compounds.

1 mol of Nickel (Ni) is made of  6.022 x 10²³ atoms of Ni

therefore 2.00 mol of Ni is made of  6.022 x 10²³ x 2.00 = 1.20 x 10²⁴ atoms of Ni

therefore 2.00 mol of Ni is made of 1.20 x 10²⁴ atoms of Ni
