Answer:
0.0560 mol
Explanation:
You need to use the ideal gas law equation:
P = 750 torr
V = 1.35 L
n = moles
R = 62.364 L torr
T = 17.0 ˚C + 273.15 = 290.15 K
Rearranging the equation for n:
n = 0.0560 mol
Answer: <span>9330 j/mol

The temperature of the gas is 475 ° Celcius which is equal to: 475 +273= 748 °K. The formula for kinetic energy of individual atoms would be
K= 3/2 * kB * T
If kB is 1.38 * 10^-23 J/K and 1 mol is made from 6.02*10^23 molecule, then the kinetic energy of 1 mol CO2 would be:
K= 3/2 * kB * T
K= 3/2 * 1.38 * 10^-23 * 748 * 6.02 *10^23 =9324 J/mol
Answer:
The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance
Explanation:
To determine the average atomic mass, we require abundance of every isotope in the nature.
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
