You collected a tissue specimen that you would like to preserve by freeze drying. To ensure the integrity of the specimen, the temperature should not exceed -10.5C. The vapor pressure of ice at 273.16K is 611 Pa; delta (fusion) H knot = 6.01 kJ/mol and delta (vaporaization) H knot = 40.65 kJ/mol. What is the maximun pressure at which the freeze drying can be carried out
