Ninhydrin forms a pink-colored compound when it reacts with amino acids left in a fingerprint. The solution is prepared by mixing 6.00 g of ninhydrin with 1000.0 mL of acetone. What is the molarity of ninhydrin, given its chemical formula is C9H6O4?
A large flask with a volume of 936mL is evacuated and found to have a mass of 134.66 g. it is then filled to a pressure of 0.967atm at 31 C with a gas of unknown molar mass and then reweighed to give a new mass of 135.91 g. what is the molar mass ..
Calculate the molar density at this pressure at 310. What fraction of the gas phase molecules initially present for 1.0 in the chamber are present at
