When a certain metal is illuminated with light of frequency 6.00 1015 Hz, a stopping potential of 8.80 V is required to stop the ejected electrons.

When a certain metal is illuminated with light of frequency 6.00 × 1015 Hz, a stopping potential of 8.80 V is required to stop the ejected electrons. What is the work function of this metal in eV ?(Notice that the stopping potential is the minimum potential difference required to bring the electrons with the maximum kinetic energy to a complete stop.)
