Explanation:
Detailed explanation-1: -The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02×1023 water molecules in a mole of water molecules. There also would be 6.02×1023 bananas in a mole of bananas-if such a huge number of bananas ever existed.
Detailed explanation-2: -Hence an atom is made up of three particles called electrons, protons and neutrons and 1 mol exactly contains 6.02214076×1023 atoms or particles. Thus 2.11×1024 atoms are present in 3.5 mol of arsenic.
Detailed explanation-3: -0.35 mole = 2.1x1023 molecules.
