Question
Convert the moles of CO2 released from the glucose reaction calculated in question 3 to the moles of glucose consumed using the following equation. m = n / 2s where m is the number of moles of sugar consumed, n is the number of moles of CO2 produced, and s is the number of simple sugars in that sugar. Record your results for use in a later question. As measured volumes will vary slightly, pick the answer that is closest to yours. The glucose reaction I got in my lab was (4.2) im not sure if they are asking for that. A. 8.571 × 10-5 moles glucose B. 1.714 × 10-4 moles glucose C. 4.286 × 10-5 moles glucose D. 1.714 × 10-1 moles glucose. I dont understand I have the temperature, I gave the glucose reaction, I even provided question 3. I'm lost what else needs to be giving??
Here is question 3 as well, not sure if this is what is needed to solve the problem.This is question 3- "Convert the volume of CO2 you measured in the glucose reaction to moles of CO2 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 CO2, n is the number of moles of CO2, R 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".
Actions I preformed during the Lab"Take the 5% glucose solution from the Materials shelf and add 50 mL to the Erlenmeyer flask. Double-click on the Erlenmeyer flask and rename it “5% glucose"
Gas volume is (4.2)
I Used 50 mL of glucose
temperature is 299.1
Explanation / Answer
volume of CO2= 4.2 mL (as you said)
volume of CO2 = 4.2*10^-3 L
n= P*V/(R*T)
= 1atm * 4.2*10^-3 L / (0.0821 * 299.1 K)
= 1.71*10^-4 mol
1 mol of glucose gives 6 mol of CO2
So moles of glucose = 1.71*10^-4/6 = 2.85*10^-5 mol
This should be the answer under ideal condition
I hope u understand the process. Answer may be coming wrong due to incorrect measured volume
