Expert Answer

Step 1

Mass of water = 368g

Specific heat of water = 4.184 J/go ...

The q is calculated as follows,
q-(mass) (At) (C)
q-(368g) (5.00°C) (4.184 J/g°C)
q= 7698.56 J
The energy is calculated as follows,
E hv
C
V=
E hx
c 3x10 m/s
h 6.626x10 (Planck constant)
-34
3x10 m/s
E 6.626x10-34,
1.06x104 x109m
E 1.8752x1020 J/photon
