Answer:
Hydrogen
Explanation:
Hydrogen has only 1 proton and has an atomic mass of 1. It does not have neutrons. Helium and above have higher mass than Hydrogen.
Looking at the formula, each mol of P4O10 contains 4 mol of P, so
(58.5 mol P4O10) x (4 mol P/ 1 mol P4O10) = 234 mol
The answer would be hypotheis since its an theory that isnt proven yet which would involve a scientist to expertiment to make the hypothesis true or valid
