Based on the amounts of reagents specified in this experiment, calculate the theorectical yield of asprin (180g/mol) in terms of moles and grams.
A 24.0 g sample of nitrogen gas reacts with an excess of hydrogen gas to give an actual yield of 3.85 g NH3. What is the percent yield for this reaction? Reaction: N2(g) + 3 H2(g) ? 2 NH3(g)
Calculate the number of moles of gas in a 3.24 L basketball inflated to a total pressure of 24.3 psi (pounds per square inch) at room temperature (25 degrees Celsius).
the equilibrium constant for the reaction at 900 degrees Celsius is .082. a reaction is intiated with only cocl2 in a 2.0-L vessel. at equilibrium 2.36*10^-3 mol is present. how many moles of cocl2 were present initially?
Ozonolysis from unknown compound, A compound, A, c6h8, yields a single organic product, B, upon ozonolysis and absorbs two moles of hydrogen on catalytic hydrogenation to give C.
A balloon filled with helium gas has a volume of 500 mL at pressure of 1 atm. The balloon is released and reaches an altitude of 6.5 km, where the pressure is 0.5 atm.
