at 25 C and 1.0 atm, .25 g of a gas dissolves in 1.00L of water. what mass of the gas dissolves in 1.00L of water at 25C and 3.0 atm
At a particular temperature , 35.0% of ClO2 molecules have speeds exceeding 400 m/s. If ClO2 is decomposed to Cl2 and O2 and the resulting mixture is cooled until the original temperature of the ClO2 is reached
The 1H NMR indicates there are three non-equivalent types of hydrogen atoms in your final compound with peaks at ~ 7.30 (m), 4.30(s), and 3.90(s) ppm. The three non-equivalent types of hydrogen atoms are aromatic hydrogens, methylene hydrogens
The resulting solution freezes at 26.5 oC. If Kf for the solvent is 1.74 o C/m then determine the molar mass of the nonelectrolyte compound?
