In ‘General Gas Equation PV=nRT’, ‘n’ represents the number of moles of gas.
Which of the following represents the relation of ‘n’?
- A
n = NNA
- B
n = N/NA
- C
n = NA/N
- D
n = N + NA
The mathematical equation is: N = n × NA, n= N/ NA
This option is incorrect as per the formula
n = NNA: This would mean the number of moles is the total number of molecules multiplied by Avogadro's number, resulting in a very large and incorrect value for the number of moles.
The mathematical equation is: N = n × NA, n= N/ NA
This option is incorrect as per the formula
n = NA/N: This would represent the inverse of the number of moles, which is not what 'n' signifies in the ideal gas equation.
This option is incorrect as per the formula
n = N + NA: This suggests that the number of moles is the sum of the total number of molecules and Avogadro's number, which is dimensionally incorrect and doesn't represent the relationship between moles, molecules, and Avogadro's number.
