In a chemical reaction or change, the final produce can not be separated or turned back into its original substance you started with.
Answer:
1.5 x 10¹⁴
Explanation:
For the nucleus :
= radius of proton = 1.0 x 10⁻¹⁵ m
= mass of proton = 1.67 x 10⁻²⁷ kg
density of nucleus is given as
= 3.98 x 10¹⁷
For the atom :
= radius of atom = radius of proton + radius of orbit = (1.0 x 10⁻¹⁵ + 5.3 x 10⁻¹¹) m
= mass of atom = mass of proton + mass of electron = 1.67 x 10⁻²⁷ + 9.31 x 10⁻³¹ kg
density of atom is given as
= 2680.5
Ratio is given as
= 1.5 x 10¹⁴
