Calculate the amount of heat required to completely sublime 63.0 g of solid dry ice CO2 at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 C.
didn't I answer this once? what was wrong with my response?
What is the initial temperature?
If it is just for phase change then the formula is Q = m L
Q = 0.063 x 32.3
To calculate the amount of heat required to sublime solid dry ice (CO2), we can use the equation:
q = m * ΔHsub
where:
q is the amount of heat in Joules,
m is the mass of solid dry ice in grams, and
ΔHsub is the heat of sublimation for carbon dioxide in Joules per gram.
Given data:
m = 63.0 g
ΔHsub = 32.3 J/g
Plugging the values into the equation:
q = 63.0 g * 32.3 J/g
Calculating the product:
q = 2034.9 J
Therefore, the amount of heat required to completely sublime 63.0 g of solid dry ice CO2 at its sublimation temperature is 2034.9 Joules.
