Answer:
3-ethoxy-3-ethyl-5-methylheptane
Explanation:
In this case, we have to identify the longest chain of carbon in this case the longest chain is made with 7 carbons. Then we have to assign carbon 1. In this case, carbon 1 is the one nearest to the ethoxy group. With this in mind, we will have a methyl on carbon 5, a methyl on carbon 3 and an ethoxy group in carbon 3, so the name would be 3-ethoxy-3-ethyl-5-methylheptane.
See figure 1

The molar mass of Naphthalene is 128g/mol
Therefore; a mass of 1.64 g of Naphthalene contains'
= 1.64g/128 g
= 0.0128 moles
But, from the Avogadro's law 1 mole of a substance contains 6.022 × 10^23 particles
Therefore 1 mole of Naphthalene contains 6.022×10^23 molecules
Hence; 0.0128 moles × 6.022 ×10^23 molecules
= 7.716 × 10^21 molecules
