To go from grams to atoms, you first have to convert to moles and them to atoms. To do that, divide the amount in grams by the atomic weight (141.95 in this case) and then multiply by avagadros number (6.022×10^23). After you do all of this, you should get 8.06×10^20.

Answer:
Explanation:
Carbon-14 has a mass number of 14, and Carbon-12 has a mass number of 12. Every carbon atom must have six protons, so Carbon-14 has eight neutrons and Carbon-12 has six neutrons. Elements with the same atomic number but different atomic masses are isotopes.
Answer:
The answer to your question is V2 = 1.3 l
Explanation:
Data
Pressure 1 = P1 = 1.5 atm
Volume 1 = V1 = 2.50 l
Temperature 1 = T1 = 22°C
Pressure 2 = P2 = 3 atm
Volume 2 = V2 = ?
Temperature 2 = T2 = 35°C
Process
1.- Convert temperature to °K
T1 = 22 + 273 = 295°K
T2 = 35 + 273 = 308°K
2.- Use the combine gas law to solve this problem
P1V1/T1 = P2V2/T2
-Solve for V2
V2 = P1V1T2 / T1P2
3.- Substitution
V2 = (1.5 x 2.5 x 308) / (295 x 3)
4.- Simplification
V2 = 1155 / 885
5.- Result
V2 = 1.3 l
