What is the frequency of radiation with a wavelength of 4.2x10^-7m

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)

Ican't see the chart but the density of both nickel and cobalt is 8.90 g/cm3, so it would be one of those.

There are two molecules. check the attached file for the solution.
