The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons. A proton is positively charged.
By use of avogadros law which state that equal volume of gas at the same pressure and volume have the same number of molecules. The avogadros constant = 6.023 x10^23 for 1 moles what about 1.14 x 10^24
= 1.14 x 10 ^24 / 6.023 x 10^23=1.893moles
Answer: 1.2 Moles of Nickel
Explanation:
So you have to transfer grams to moles.
You do this by dividing your beginning mass by the atomic mass of the element (found on the periodic table).
1 mole is equal to the atomic mass of the element. The atomic mass of Nickel is 58.6934 rounded to the proper significant figures will be 59.
72 Grams Nickel / 59 grams = 1.2 moles of Nickel
