Answer:
Average Molar mass is 114.8u
Explanation:
» From the formula of average Relative Atomic Mass [ RAM ]
» We have two isotopes of Indium,
- Indium-113, mass » 112.9u, % » 4.28%
- Indium-115, mass » 114.9u, % » 95.72%
Answer:
The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000
Multiply the amount of moles (0.075mol) by Avagadro's number (6.02x10^23 atoms/mol) to get 4.5x10^22 atoms.
Answer:
1.13 moles Au
Explanation:
Moles Au = 6.80x10²³atoms / 6.023x10²³atoms/mole = 1.13 moles Au
