General Chemistry - A quantity of 5.25 g of NaOH is dissolved in a sufficient amount of water to make up exactly 1L of solution. What is the molarity of the solution?
Dissolved oxygen question w/hint - A ground water sample , at 25 degrees C, has Eh= 1.0 and pH=6.80. Assuming the system is at equilibrium, calculate the amount of dissolved oxygen (ppm) in the groundwater sample
Hint: [O2-aq]/[O2-g ...
Conversions of oxygen radicals from ppmv - During a photochemical smog episode in a coastal city, the steady-state concentration of oxygen radicals at ground level was measured to be 0.09 ppmv at 25 degrees celsius. Convert this value to:
a. ...
Concentration of atmospheric CO2 - If the concentration of atmospheric CO2 were to double from its current value of 330 ppm, what would be the calculated pH of rainwater assuming that CO2 was the only acidic input? Please show step by ...
Conversion problem - I prepared a 1.0 mM solution of Benzoic Acid in methanol and I now need to convert it to 50ppm. ????
How???
