Question

Equation # 1: 2 NaHCO3 --->NA2O3+H2O+CO2

1. weight of NaHCO3 = 3 grams

2. weight of test tube and contents before heating = 44.22 grams

3. wieght of test tube and contents after heathing = 43.13 grams

4. weight of H2O and CO2 produced= 1.09 grams

5a. grams of CO2 produced (calculate using equation #1) = ________ grams

5b. Moles of CO2 produced = __________ moles

6. volume of gas collected = 488 mL

7. tempature of water = 21.39 degrees Celceius

8. barametric pressure = 755.7 torrs

9. vapor pressure of water = 19.1 torrs

10. actual perssure of CO2 (dry) = 736.6 torrs

Using Results from above:

1a. Calcuate theoretical volume of CO2 produced at STP: ______ Liters

2a. Calculate theoretical volume of CO2 produced using the data above: _____ Liters

3a. Percent error using 1a = ____ %

3b. Percent error using 2a = ____ %

I need help with 5a, 5b, 1a, 2a, 3a and 3b!!!
