The director of the university laboratory left unexpectedly due to an emergency in Friday. When he returned on Monday, he discovered that he had left a container of a
liter of aqueous solution of pure NaOH with initial concentration c0 = 0.1 M. Being in
In contact with air, the solution has absorbed atmospheric carbon dioxide CO2 (g).
Data: H2CO3: pKa1 = 6.37; pKa2 = 10.25. T = 22 ° C; P = 1 atm.
I) Write the balanced chemical equation of (1) the formation of carbonic acid and (2) the
sodium hydroxide neutralization.

It would be true sodium reacts with water in a violent way

Use the universal gas law formula: pv = nrt now, the key word in this problem is stp, so at stp, temperature will always be 0 degrees celsius and pressure will always be 1.0 atm or 760 torr. given something is at stp, we already know the two variables pressure and temperature. the other thing we can find with the given information is moles. to find moles, just divide grams by molar mass of the element. 16.0g / 2(16.00)g/mol = 0.5 moles plug the values in to the equation pv = nrt (1.0 atm)( x ) = (0.5 )(0+273=273k) the r value is just a constant for when we use atm, liters, moles and kelvin. i'm assuming you want your answer in liters, but if you dont just move the decimal 3 to the right in your final answer. so when plugging these numbers in to your calculator and trying to find x, you get 11.20665 liters using significant figures the answer is 11.2 liters
