GPT 3.5
To calculate the mass of metal that burns to produce an enthalpy change of -9.00 * 10^4 kJ, we need to know the specific enthalpy change (ΔH) of combustion for the metal.
The equation for calculating the mass of metal is:
Mass = ΔH / ΔH of combustion
Assuming the specific enthalpy change of combustion is known, let's say it's -400 kJ/g (this value will vary depending on the metal), we can now calculate the mass of metal as follows:
Mass = (-9.00 * 10^4 kJ) / (-400 kJ/g)
Dividing -9.00 * 10^4 kJ by -400 kJ/g, we can cancel out the kJ units:
Mass = (9.00 * 10^4) / 400 g
Mass = 225 g
Therefore, the mass of metal that burns to produce an enthalpy change of -9.00 * 10^4 kJ is 225 grams.
