6. You must divide the mass by it’s molar mass to give you the total amount of moles within that piece. This will give you approx 0.05mol. You can now multiply this value by Avagadros constant which gives you 2.93 x 10^22 atoms. I would expect gold to have less atoms as it’s molar mass is higher than that of silvers, meaning that less atoms would be required to equal the same mass
The iupac name of the compound will be hex-3-yne or 3-hexyne. By marking number of carbon in the given compound, it was found that triple bond comes at third position and there are total 6 carbon in the compound. So it will have Hex as a prefix and as it contains triple bond so it will have yne as a suffix and as the triple bond is at third position, so it will be hex-3-yne or 3-hexyne.
a) Number of protons = number of electron in the atom = atomic number
So it has 7 protons answer
N-3 has gained 3 electron so number of electrons + 7+3
= 10 answer
