    Hi, newbie here.

    I'm doing my GCSE coursework, and I have forgtten how, in the experiment, I altered the concentration of CO2 in sodium hydrogen carbonate solution. I started off with 0.1mol then 0.05mol, 0.025mol, 0.0125mol, 0.00625mol.

    I would greatly appreciate any help as quickly as possible.

    Thanks

    I did! But I've lost one page of my notes.

    What I need to know is how much sodium hydrogen carbonate is needed to contain 1mol of co2. Could someone please tell me, and show me the working?

    Also, When I was investigating the rate of photosynthesis, the test tube containing the elodea and sudium hydrogen carbonate solution was placed in warm water, any idea why.
