Question

A solution is prepared by adding 6. 24 g of benzene (c 6h 6, 78. 11 g/mol) to 80. 74 g of cyclohexane (c 6h 12, 84. 16 g/mol). Calculate the mole fraction of benzene in this solution.

Step-by-step explanation:

A particular metal has a work function of 1. 05 ev. A light is shined onto this metal with a corresponding wavelength of 324 nm. What is the maximum velocity of the photoelectrons produced? (hint: 1ev = 1. 6022 x 10-19 j, mass of an electron = 9. 11 x 10-31 kg).A particular metal has a work function of 1. 05 ev.
