Predict the gravitational and electrostatic forces between molecules of gases? Provide evidence for your prediction.
zmey [24]

the electrostatic forces are 10^{36} larger than the gravitational force

Explanation:

Let's do the calculation by using two molecules of hydrogen, each containing 2 atoms of hydrogen.

The gravitational force between the two molecules is given by:

F=\frac{G m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1 and m2 are the masses of the two molecules: since they are identical,

m_1 = m_2 = 2m_p = 1.67\cdot 10^{-27} kg, twice the mass of the proton

r is the distance between the two  molecules

The force can be rewritten as

F_G=\frac{Gm_p^2}{r^2}

We can assume instead that electrostatic force between the two molecules is given by the interaction between the positively charged nuclei and the neatively charged electrons. Therefore,

F_E=\frac{kq_1 q_2}{r^2}

where

k=8.99\cdot 10^9 Nm^{-2}C^{-2} is the Coulomb's constant

q_1 = q_2 = 2e is the magnitude of the charge of each molecule, where

e=1.6\cdot 10^{-19}C is the fundamental charge

r is the distance between the two molecules

So the force can be  rewritten as

F_E=\frac{ke^2}{r^2}

Therefore, the ratio between the two forces is:

\frac{F_E}{F_G}=\frac{ke^2}{Gm_p^2}=\frac{(8.99\cdot 10^9)(1.6\cdot 10^{-19})^2}{(6.67\cdot 10^{-11})(1.67\cdot 10^{-27})^2}\sim 10^{36}

So, the electrostatic forces are 10^{36} larger than the gravitational force.

Three mixtures were prepared from three very narrow molar mass distribution polystyrene samples with molar masses of 10,000, 30,
8_murik_8 [283]

Answer:

(a). 46,666.7 g/mol; 78,571.4 g/mol

(b). 86950g/mol; 46,666.7 g/mol.

(c). 86950g/mol; 43,333.33 g/mol

Explanation:

So, we are given the molar masses for the three samples as: 10,000, 30,000 and 100,000 g mol−1.

Thus, the equal number of molecule in each sample = ( 10,000 + 30,000 + 100,000 ) / 3 = 46,666.7 g/mol.

The average molar mass = [ ( 10,000)^2 + (30,000)^2 + 100,000)^2] ÷ 10,000 + 30,000 + 100,000 = 78,571. 4 g/mol.

(b). The equal masses of each sample = 3/[ ( 1/ 10,000) + (1/30,000 ) + (1/100,000) ] = 20930.23 g/mol.

Average molar mass = ( 10,000 + 30,000 + 100,000 ) / 3 = 46,666.7 g/mol.

(c). Equal masses of the two samples = (0.145 × 10,000) + (0.855 × 100,000)/ 0.145 + 0.855 = 86950g/mol.

The weight average molar mass = 1.7 + 10,000 + 100,000/ 1.7 + 1 = 43,333.33 g/mol.
