Explain how you would find the number of moles of carbon in 4.5 kg of carbon.
UkoKoshka [18]
In a simplified version, check the number carbon atoms present and multiply by its relative atomic mass. Later divide by the given mass (4.5 x 1000 = 4500g) and you’ll get the number of mole of carbon

Calculate the solubility of carbon dioxide in water at an atmospheric pressure of 0.400 atm (a typical value at high altitude).A
Bond [772]

Answer:

The molar solubility of carbon dioxide gas is 4.662\times 10^{-6} M.

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

C_{CO_2}=K_H\times p_{liquid}

where,

K_H = Henry's constant = 3.50\times 10^{-2}mol/L.atm

p_{CO_2} = partial pressure of carbonated drink

p_{CO_2}=p\times \chi_{CO_2}

where = p = Total pressure = 0.400 atm

\chi_{CO_2} = mole fraction of CO_2=3.33\times 10^{-4}

p_{CO_2}=0.400 atm\times 3.33\times 10^{-4} =0.0001332 atm

Putting values in above equation, we get:

C_{CO_2}=3.5\times 10^{-2}mol/L.atm\times 0.0001332  atm\\\\C_{CO_2}=4.662\times 10^{-6} M

Hence, the molar solubility of carbon dioxide gas is 4.662\times 10^{-6} M.
