Iodine, i2, is a solid at room temperature but sublimes (converts from a solid into a gas) when warmed. what is the temperature (in k) in a 71.4 ml bulb that contains 0.276 g of i2 vapor at a pressure of 0.478 atm?

382.63 K

We are given;

We are required to calculate the temperature of Iodine

T = PV ÷ nR

But, n, the number of moles = Mass ÷ Molar mass

Molar mass of iodine = 253.8089 g/mol

Thus, n = 0.276 g ÷ 253.8089 g/mol

           = 0.001087 moles

Therefore;

T = (0.478 atm × 0.0714 L) ÷ (0.001087 moles × 0.082057)

  = 382.63 K

Thus, the temperature of Iodine in Kelvin is 382.63 K

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

the temperature of the gas, in k, not celsius.
