HCl + NaHCO3 = NaCl + H2O + CO2
We have 0.033*0.2 = 0.0066 mol of Hcl
According to reaction we need the same amount of NaHCO3
M(NaHCO3) = 23+1+12+48=84g/mold
m = 0.0066mol * 84g/mol = 0.5544g
Convert 50mL to liters by dividing it by 1000 to get your liters value which should be 0.05 L
Now your formula is .20 = x/0.05
Solve for x to get your mol value and you should get 0.01 mol
Answer: The average potential energy of the PIB is 0 irrespective of the wave function.
Explanation:
⟨H⟩=⟨KE⟩+⟨V⟩
the nn quantum number
⟨KE⟩=(π^2 ℏ^2)/(2mL^2 )
the average kinetic energy of the wavefunction is dependent on
⟨V⟩=∫sin(kx)0sin(kx)dx=0
The average potential energy of the PIB is 0 irrespective of the wave function.
⟨H⟩=⟨KE⟩=(π^2 ℏ^2)/(2mL^2 )
