1 o1 20 ne Introduction to the Ideal Gas Law Submit My Answers Give Up Learning Goal: Correct To apply the ideal gas law to problems invohing temperature. pressure, volume, and moles of a gas The four properties of gases (pressure P, volume V Part D temperature T, and moles of gas n)-re related by a single expression known as the ideal gas law A 10 0 I gas cylindes has been filled with 6,80 moles ol gas. You measure the pressure to be 3.00 atm What s the temperature inside the tank? Express your answer to three significant tigures and include the appropriate units The variable R is known as the unvivevsal gas constant and has the value R=0.0821 L atm/(mole-K) The units of R dictate the units for all other quantities, so when using this value al R use units of atmospheres for pressure, liters lor volume, and kelwins for temperature Hints raak 1 Value Units Submit My Answwers Give Up Incorrect: Try Again 5 attempts remaining Continue 2:57

Explanation / Answer

D)

V = 10 L

n = 6.8

P = 3 atm

find T

Apply Ideal Gas Law,

PV = nRT

where

P = absolute pressure

V = total volume of gas

n = moles of gas

T = absolute Temperature

R = ideal gas constant

PV/(nR) = T

T = (3*10)/(0.082*6.8) = 53.802 K

T = 53.802 K

if °C is required --> 53.802-273 = - 219.198°C
