At a temperature of °c, 0.444 mol of co gas occupies 11.8 l at 889 torr.

Explanation: IDEAL GAS LAW

where,

P = pressure of the gas  = 889 torr = 1.17 atm    (1 torr=0.0013atm)

V = volume of the gas  = 11.8 L

T = temperature of the gas  = ? K

n = number of moles of gas  = 0.444

R = Gas constant = 0.0821 Latm/moleK

Thus temperature of gas is

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.
