Explanation:
Given: 56.2 mL of gas
To find: volume that 56.2 mL of gas at 820 mm of Hg would occupy at 720 mm of Hg
Solution:
At 820 mm of Hg, volume of gas is 56.2 mL
At 1 mm of Hg, volume of gas is
At 720 mm of Hg, volume of gas is
Answer:
(a) Wavelength = 4.85 x 10^-12 m
(b) Maximum uncertainty = 5.27*10^-25 kgm/s
Explanation:
(a) Calculating the wavelength using the formula;
λ= h/p
but p = mv
Where;
m = mass of electron = 9.1 x 10-31
h = 6.625 x 10^-34
= h/mv
= 6.625 x 10^-34 / (9.1 x 10^-31 x 1.5×10^8)
= 4.85 x 10^-12 m
so, the wavelength is short enough to reveal molecular details at the atomic level.
(b) Find attached of part b
