yes we reacted each on with vinegar until there was no more bubbles and found how many g of CO2 were evaporated we used a pipet filled with vinegar and weighed it in with unreacted setup and then weighed it in with reacted setup so that only missing mass was the CO2

we did it with CaCo3 and NaHCO3 it wouldn't let me space the chart out so it would scrunch it all together so i used ... to separate them if i no how to do one i can get the other easily

molar mass of CO2 is 44g/mol molar mass of CaCO3 is 100g/mol 1g/100g/mol=x/44g/mol x=.44g .44g of CO2 makes up CaCO3? so .44g divided by 44= .01mols? idk I am prolly really wrong

i ment i end up with .01 not .44 what i do is i find that CO2 makes up .44g of the 1g ofCaCO3 then i divided .44g by 44g and got .01mols when i did it in the lab only .o5g evaporated not .44g? is the work i did correct or the lab correct?

sry i forgot a 2 i just edited it in so its balanced now sry

ya i get that so the ration of CaCO3 and CO2 is like 1:1? well i think i know what to do but i end up with something like .44mols and what we did in class for the lab makes out to be .0011mols i don't get how to get how many grams of CO2 is in 1g CaCO3 if that's what I am supposed to do...

:confused: well the balanced equation would be for the CaCO3 reaction would be CaCO3+2HC2H3O2=>Ca(C2H3O2)2+CO2+H2O molar mass of CaCO3 is about 100g/mol and CO2 is 44g/mol but i don't no what to do from here or what ratios u r talking about im sry my teacher didnt explain this at all and...
