What volume is occupied by 8.6 g
of nitrogen gas, N2, at 23°C
and 1.15 atm pressure?
Volume = --- L
31-The heat of vaporization of liquid Freon-12,
CCl2F2, is 4.71 kcal/mol. Calculate the
energy required to vaporize 67.7 g of
this compound. The molecular weight of Freon-12 is 120.9 amu.
------ kcal
33-Compare the number of calories absorbed
when 245 g of ice at 0°C is changed to
liquid water at 37°C with the number of calories absorbed
when 245 g of liquid water is warmed
from 0°C to 37°C.
amount of heat = ------cal
