1mg NaCl to 100ml would would yeild a 1% solution. (assuming pure NaCl), now if you talking about molarity then that may be a bit different.

Sounds like a titration? If you got an air bubble then the volume effectively changes, therefore the number of moles delivered is changed as well. MLS (ASCP) MB

If I understand your experiment, it sounds like as the carbonation comes out of the pop it is contained in the test tube and the pressure pushes the pop out of the test tube and into a beaker? The principle here is there is carbon dioxide that...

if you have a solution whose concentration is given in moles, you don't even need the molar mass to do this! your concentration was 0.200 but you left out the units.. a common reason why people get confused.. it is 0.200 moles per litre so...
