Answer : The number of molecules present in nitrogen gas are,
Explanation :
First we have to calculate the moles of nitrogen gas by using ideal gas equation.
where,
P = Pressure of gas =
(1 atm = 760 mmHg)
V = Volume of gas = 985 mL = 0.982 L (1 L = 1000 mL)
n = number of moles = ?
R = Gas constant =
T = Temperature of gas =
Now put all the given values in above equation, we get:
Now we have to calculate the number of molecules present in nitrogen gas.
As we know that 1 mole of substance contains number of molecules.
As, 1 mole of gas contains
number of molecules
So, mole of
gas contains
number of molecules
Therefore, the number of molecules present in nitrogen gas are,
