Answer:

Mass of copper vaporized is 52,8g

Explanation:

The heat of vaporization (ΔHvap) is defined as the amount of energy you require to transform a quantity of liquid in gas. The formula is:

Q = ΔHvap×mass

Where Q is the amount of heat and mass is the mass of the compound.

If you required 254 kJ to vaporize a sample of copper which heat of vaporization is 4,81 kJ/g:

254kJ = 4,81 kJ/g × mass of copper

<em>52,8g = mass of copper</em>

<em></em>

I hope it helps!
