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.
heat= heatsublimation*mass
I am not certain what your units are on the heat of sublimation, but they need to be in Joules/gram.
To calculate the amount of heat required to completely sublime 63.0 g of solid dry ice (CO2), we need to use the equation:
q = m·ΔHsub
Where:
q is the heat required (in joules),
m is the mass of the substance (in grams), and
ΔHsub is the heat of sublimation (in J/g).
Given:
m = 63.0 g (mass of solid dry ice)
ΔHsub = 32.3 J/g (heat of sublimation for carbon dioxide)
We can plug these values into the equation to calculate the amount of heat required:
q = 63.0 g · 32.3 J/g
= 2034.9 J
Therefore, the amount of heat required to completely sublime 63.0 g of solid dry ice at its sublimation temperature is 2034.9 Joules.
Convert grams to moles. (85)/(12+16+16)=1.93182
1.93182*32.3=62.3977
