Question

iodine sublimes by turning from a solid to a vapor when heated. a 100g sample of solid i2 is put in an empty rigid 10 l container and heated to 325k. when al the solid i2 vaporizes what is the pressure(in atm) in the container

Answer 1

`\boxed{\text{1.05 atm}}`

Step-by-step explanation:

We can use the Ideal Gas Law to calculate the pressure.

pV = nRT Divide both sides by V

p = (nRT)/V

p = (m/M)(RT/V) = (mRT)/(MV)

Data:

m = 100 g

R = 0.082 06 L·atm·K⁻¹mol⁻¹

T = 325 K

M = 253.81 g·mol⁻¹

V = 10 L

Calculations:

p = (100 × 0.082 06× 325)/(253.81 × 10) = 1.05 atm

The pressure in the container is
`\boxed{\text{1.05 atm}}`.
