I think the correct answer from the choices listed above is option A. The three components of air are all <span>classified as pure substances since they are not chemically bonded so they can be separated by certain processes and be present as a pure substance. Hope this answers the question.</span>
Answer:
260.52 g
Explanation:
The Molar Mass of Angelic Acid ( C5H8O2) is 100.2g/mol, so if we multiply the molar mass by 2.6 mols, we should get 260.52g.
Empirical formula = mol ratio
mol H = 9.42 x 10²⁴ : 6.02 x 10²³ = 15.648
mol N = 3/9 x 15.648 = 5.216
mass N = 5.216 x 14 g/mol =73.024 g
physical
It can be chemical but it's usually physical as the molecular structure doesn't change
