The "c" represents in specific heat in this question.
Q is the total energy, m is the mass, c is the specific heat capacity, and t is the temperature change. This equation is the equation for calculating about the total energy given out of absorbed when a temperature of a substance changes.
For example, if we want to know how much heat is absorbed by 1 kg of water for it to rise by 10 degrees, we can calculate by using the specific heat of water, which is around 4200 J kg-1 °C-1. So the total heat absorbed would be 1 x 4200 x 10 = 42000 J.
Answer: The energy of a mole of photon associated with this frequency is 
Explanation:
The energy and frequency are related by :
E = energy of photon
N = number of moles = 1
h = planks constant = 
= frequency = 
The energy of a mole of photon associated with this frequency is
Answer: 177g
Explanation:
Aw 12 = 6.02214076*10^23 atoms
mass = 12*88.70^23/6.022*10^23
