A 45.3 g sample of potassium nitrate is dissolved in enough water to make 225 mL of solution. Determine the molar concentration of the potassium nitrate.
If 100 mL of a solution containing 0.001 g of a compound with a molecular weight of 150 has a measured absorbance in a 1-cm cell of 2.0, what is the compound's molar extinction coefficient?
A buffer solution is prepared by mixing 47.5 mL of 0.772 M carbonic acid with 58.8 mL of 0.0346 M sodium hydrogen carbonate. 1. Calculate the pH (to two decimal places) of this solution. Assume the 5% approximation is valid and that the volumes are a..
Explain why magnesium metal is more reactive than aluminum metal yet they are in the same period of the periodic table?
