Hi Dr. Mona, your video was absolutely helpful! For the experiment, can I say that I'm heating the measuring cylinder using a thermostatically controlled water bath instead of the bunsen burner? Thanks
hi ms, had a quick q here... in the apparatus change q cant we mention pipette as the volume is fixed at 30cm3 so we can directly take a 30cm3 pipette cant we? and cant we use a balance as well to measure the mass of the lithium crystals?
It is just cross multiplication (1)Volume of the sample(known ) ----》volume of co2 gas in the sample ( known) (2) 1dm3 ---------》 ??CO2( unknown volume) So the unknown volume = 1dm3 × co2 (collected from ur sample ) divided by volume of the Sample
