What volume (in L) of a 3.95 M potassium chloride (KCI) solution would be needed to make 325 mL of a 2.76 M solution by dilution?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

What type of radiation is lead emitting in the following equation? alpha particles beta particles gamma rays

If i had 2 m naoh solution, what does the 2 m stand for? 2 molar, but 2 of a solute in 1
