Answer:
P = 2.25 atm
Explanation:
Given data:
Mass of dry ice = 10 g
Volume of container = 2.5 L
Temperature = 25°C (25+273=298 K)
Pressure inside container = ?
Solution:
First of all we will calculate the number of moles of dry ice.
Number of moles = mass / molar mass
Number of moles = 10 g/ 44 g/mol
Number of moles = 0.23 mol
Now we will determine the pressure.
PV = nRT
P = nRT/V
P = 0.23 mol × 0.0821 atm.L/mol.K × 298 K / 2.5 L
P = 5.63 atm / 2.5
P = 2.25 atm
