What is the mass of mercury, to which the amount of heat of 600 kJ was reported during boiling?

What is the mass of mercury, to which the amount of heat of 600 kJ was reported during boiling? specific heat of vaporization of mercury 0.3 * 1,000,000 J / kg

From the problem we know that:
600 kJ = 600,000 J;
Now let’s write down the basic formula for solving the problem:
Q = c * m;
Therefore, we can express m, from the formula above:
m = Q / c;
Let’s substitute the values into the formula:
m = 600000 / 0.3 * 1000000 = 600000/300000 = 2.
Answer: 2 kg
