Question

'Relative atomic mass of sulfur is 32u'.What do you understand by this statement?

Answer 1

Relative atomic mass of sulphur means that atomic mass of sulphur is 32 times heavier than the mass of 1/12 of carbon-12 atom. It doesnt mean that 32 is the actual mass of sulphur.

hope it helps...

Answer 2

by this we understand that the mass of sulphur is relative to the standard mass u.
the standard mass is the 1/12 of the atomic mass of carbon 12 isotope..
thus mass of one proton or neutron = 1/12 of carbon 12 isotope that is 1i
so number of protons = 17
this number of neutrons = 18
thus mass = 17+18= 35
