A biochemical engineer isolates a bacterial gene fragment and dissolves a 19.6 mg sample of the material in enough water to make 37.9 mL of solution. The osmotic pressure of the solution is 0.340 torr at 25°C.
an undergraduate researcher in a biology lab produced a buffer solution by dissolving sodium dihydrogen phosphate (Ka = 6.2 × 10-8) and sodium hydrogen phosphate (Ka = 3.6 × 10-13) together in an aqueous solution. What mole ratio of Na2HPO4/NaH2PO..
Consider the gas phase reaction 2 HCL = H2 + Cl2 for which Kc = 16 at 523 Kelvin. If .030 moles of HCl is introduced into a 1 L vessel at 523 K
What would happen if too much triethyamine was added to the reaction? Also if you added too much acrylic acid?
We performed this lab, but I'm having trouble taking the data collected and calculating the total concentration of both Ca2+ and Mg2+, along with the individual concentration of each.
The normal boiling point of water (delta H vap = 40.7 kJ/mol) is 100c. At the summit of mount Everest the boiling point of water is 70 c. Calculate the pressure in (torr) at the summit of Mount Ev.
