Let the cold water go up x degrees.
Let the hot water go down 100 - x degrees.
The formula for heat exchange is m*c*delta t
Givens
Ice
deltat = x
m = 0.50 kg
c = 4.18
Hot water
deltat = 100 - x
m = 1.5 kg
c = 4.18
Formula
The heat up = heat down
0.50 * c * x = 1.5 * c * (100 - x)            Divide both sides by c
Solution
0.50 *x = 1.5*(100 - x)                          Remove the brackets.
0.5x = 150 - 1.5x                                  Add 1.5x to both sides.
0.5x + 1.5x = 150 - 1.5x + 1.5x             Combine like terms  
2x = 150                                               Divide by 2
x = 75

Answer:
The work function ϕ of the metal = 53.4196 x 10⁻¹⁶ J      
Explanation:
When light is incident on a photoelectric material like metal, photoelectrons are emitted from the surface of the metal. This process is called photoelectric effect. 
The relationship between the maximum kinetic energy ( ) of the photoelectrons to the frequency of the absorbed photons (f) and the threshold frequency (f₀) of the photoemissive metal surface is:
) of the photoelectrons to the frequency of the absorbed photons (f) and the threshold frequency (f₀) of the photoemissive metal surface is:
                                          = h(f − f₀)
 = h(f − f₀)
                                          = hf - hf₀
 = hf - hf₀
E is the energy of the absorbed photons:  E = hf
ϕ is the work function of the surface:  ϕ = hf₀
                                          = E - ϕ
 = E - ϕ
Frequency f = 8.12×10¹⁸ Hz
Maximum kinetic energy  = 4.16×10⁻¹⁷ J
 = 4.16×10⁻¹⁷ J  
Speed of light  c = 3 x 10⁸ m/s
Planck's constant h = 6.63 × 10⁻³⁴ Js                                
                                         E = hf = 6.63 × 10⁻³⁴ x 8.12×10¹⁸ 
                                         E = 53.8356 x 10⁻¹⁶ J
from  = E - ϕ ;
 = E - ϕ ;
                                         ϕ = E - 
                                         ϕ = 53.8356 x 10⁻¹⁶ - 4.16×10⁻¹⁷
                                         ϕ = 53.4196 x 10⁻¹⁶ J
The work function of the metal ϕ = 53.4196 x 10⁻¹⁶ J
