Solution 1

To find the mass of the object, we can use the formula for specific latent heat:

Q = mL

where: Q = heat energy required for the change of state (in joules) m = mass of the substance (in kg) L = specific latent heat (in joules per kg)

We are given: Q = 1.09 MJ = 1.09 * 10^6 J (since 1MJ = 10^6 J)
