Because the number of constitutional, conformational, and geometric isomers goes up with each carbon atom added. There are many more possible configurations and connectivities possible with decane, a 10 carbon chain, than with butane, a 4 carbon chain.
Moles = mass/molar mass, so n(C2H6O)= 16.0 / (12+12+(1x6)+16)
=0.348 (to correct sig figs)
Bro you really expect us to read that for just 5 points and we all be to lazy to read that
