What is the pH of 0.20 M NaCl 2. what is the pH of 0.20 M NH4NO3 3. What is the pH of 0.20 M NaCH3COO?
A total of 0.145 g of this subunit was dissolved in enough water to produce 2.00 mL of solution. At 28 Celsius the osmotic pressure produced by the solution was 0.138 atm. What is the molar mass of the protein?
Based on the stoichiometry, at what point does the limiting reactant change? show calculations to support your answer. The volume of acid HCL (10mL) is constant and mass of metal Mg (0.250g) is constant.
Important information about Thermochemistry, Glauber's salt, sodium sulfate decahydrate (Na2SO4 * 10H2O) undergoes a phase transition (that is melting or freezing) at a convenient temp of 32 degrees C
Calculate the pH of a buffer solution made by mixing 49 ml of a 0.07 M ammonia solution with 52 ml of a 0.10 M ammonium nitrate solution. Give the pH to two decimal places.
Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years.
