Question: For the unbalanced rxn HBR +KHCO3 --> KBR +water +Co2, how many liters of CO2 are produced at STP from 100mL of a solution made by mixing 100 g KHCO3 (100g/mole) into enough solved to form 500 mL of solution?
A)1.12L
B)2.24L
C)4.48L
D) 5.6L
Answer (highlight)': C
Problem: TOO MANY NUMBERS! I got confused SO easily. Where do I start, if this was a question on the MCAT? I'd freeze. All I can get to is converting 100g/mole to CO2 g/mole then 22.4L=1 mole. HELP!
