4. Dry ice is carbon dioxide in the solid state. 0.2987 moles of dry ice is placed ina 5.00 L chamber that is maintained at 35.1°C. What is the pressure in thechamber after all of the dry ice has sublimed (in kPa)?

Respuesta :

In this question, we will be using again the Ideal gas law formula, which is the following formula:

PV = nRT

We have:

P = ?

V = 5.00 L

n = 0.2987 moles

R = 0.082

T = 35.1°C, or 308 K

Now adding these values in the formula:

P * 5 = 0.2987 * 0.082 * 308

5P = 7.54

P = 1.51 atm, which in kPa is 153 kPa
