question 3: Convert the volume of CO_2 you measured in the glucose reaction to m

Question

question 3:

Convert the volume of CO_2 you measured in the glucose reaction to moles of CO_2 using the Ideal Gas Law to solve for n. Assume P is 1 atm. n= PV/RT where P is the atmospheric pressure in the lab, V is the volume in liters of CO_2, n is the number of moles of CO_2, P is the gas constant 0.082 L-atm/mole-Kelvin, and T is the temperature in Kelvin. Convert the gas volume to L by dividing the volume in mL by 1000. 1.914 Times 10^3 moles CO_2 1.714 Times 10^3 moles CO_2 3.428 Times 10^3 moles CO_2 1.153 Times 10^3 moles CO_2

Explanation / Answer

a.PV = nRT

V = nRT/P

    = 1.914*10-3 * 0.0821*273/1

    = 0.0429L = 42.9ml

b. PV = nRT

V = nRT/P

    = 1.714*10-4 * 0.0821*273/1

    = 0.00384L = 3.84ml

c.   PV = nRT

V = nRT/P

    = 3.428*10-5 * 0.0821*273/1

    = 0.000768L = 0.768ml

d.    PV = nRT

V = nRT/P

    = 1.153*10-5 * 0.0821*273/1

    = 0.000258L = 0.258ml
