Answer to Question #137905 in General Chemistry for mike

Question

5.600g of solid CO2 is put in an empty sealed 4.00L container at a temperature of 300K. When all the solid CO2 becomes gas, what will be the pressure in the container?

Answer 1

Use ideal gas equation

PV =nRT

given V= 4.00l

mass m = 600g 

number of mols = 600g/44.01 g/mol 

T=300 k

P =nRT/V 

= 600g* 0.0821 l atm/mol.k * 300 K/4.00 l *44.01 g/mol  

 = 83.9 atm

Answer

pressure = 83.9 atm
