Alright class. Your task is to produce 175mL of carbon dioxide. You many use anything in class. You have 1 class period to produce your product. You can use as much sodium carbonate and 1.0M hydrochloric acid as needed. ( Remember is stoichiometry lab)
Na2CO3 + 2HCl ==> H2O + CO2 + 2NaCl
You want 175 mL CO2. You know pressure and temperature of the lab. Use PV = nRT to calculate moles in 175mL CO2 at the conditions of the lab.
Using the coefficients in the balanced equation, convert moles CO2 desired to moles HCl.
Then using M = mols/L, solve for L of 1 M HCl needed.
Use the same process to determine mols Na2CO3, then convert moles Na2CO3 to grams. g = mols x molar mass.
You will need to work out the collection procedure, the lab set up, and that kind of thing.

Thank you so much!!! We do not know the pressure or temperature of the classroom though. This assignment was given to us for homework. We are to figure out the numbers and send them to our teacher then use them to do the lab in class tomorrow. Should we use a temp and pressure previously recorded in another lab?
