The mass spectrum of an organic compound shows the relative abundances of M to be 34.83% and M 1 to be 6.027%. Assuming the peaks are caused by 12C and 13C isotopes, determine the number of carbon atoms in the compound. Natural abundances: 12C is 98.93% and 13C is 1.07%
Cobalt was used as an internal standard to analyze a sample of titanium with atomic absorption spectroscopy. A mixture was prepared by combining a 4.00 mL Ti solution of unknown concentration with 3.00 mL of a 11.7 micrograms/mL solution of Co
carbon and oxygen occupies a volume of 452 ml at 63 C and 745 mmHg. identify the gas in the sample (R= 0.0821 L*atm/K*mol)
Although the double bond, in total, is stronger than a single bond, the pi bond itself is weaker and can react with electron-deficient species such as a hydrogen ion.
More gas is then added to the container until it reaches a final volume of 13.9 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
A 248 gas sample has a mass of 0.433 g at a pressure of 745 mm Hg and a temperature of 28 C. What is the molar mass of the gas?
Explain why does ATP synthesis occur in the presence of Rotenone ( an inhibitor of one the reactions in the electron transport system.) if succinate is combined but not ATP synthesis doesn't occur if L-malate is added?
a 1.628 gram sample of a hydrate of magnesium iodide is heated until all of the water is removed. its mass is now 1.072 grams. what is the formula of the hydrate?
What is the pH of a solution that is 0.10 M CH3NH2 (methylamine) and 0.15 M methylammonium chloride
