Answer:
The answer to your question is 8.75 x 10 ²⁵ atoms of Magnesium
Explanation:
Data
Atomic mass of Magnesium = 24.31 g
Atoms of magnesium = 3.60 x 10²⁴
Process
Solve this porblem using a rule of three
1 atom of Magnesium --------------- 24.31 g
3.60 x 10²⁴ ---------------- x
x = (3.60 x 10²⁴ x 24.31) / 1
x = 8.75 x 10 ²⁵ atoms
Answer: Kinetic energy is energy that is associated with the constant movement of atoms or molecules. Kinetic energy is also called thermal energy, it is a form of motion. It is the motion of waves, electrons, atoms, molecules, substances, and objects!
Hope this helps a little bit
The atomic masses written for every element in the periodic table is the average atomic weight that is calculated from the element's isotopes. The formula would be:
Average Atomic Weight = ∑(Isotope Mass×Relative Abundance)
Substituting the values:
Average Atomic Weight = (331 amu×0.35) + (337 amu×0.65)
Average Atomic Weight = 334.9 amu
The answer to the problem is
69.55
Answer:
8.18K
Explanation:
This question is solved using the ideal gas equation:
PV=nRT
where,
P= pressure
V= volume
n= no. of moles
R= gas constant(8.314 J/K/mol)
T= temperature
Since in the question, volume of the container and amount of gas is not given,we'll assume a value for these variables and substitute it in our formula;
P= 3.4 atm
V= 1 litre (assumption)
n= 5 moles (assumption)
R= 8.314
T= ?
PV=nRT
3.4*1=5*8.314*T
T=3.4*1/0.08314*5
T= 8.18K
