 |
|
hi i need to find a way to calculate the thickness of the metal zinc foil. without a balance or a ruler...chemistry must be involved.
density of metal foil > 7.13 g/cm 3
i think i can solve it using back titration...but i don't understand the method of back titration
i know the first step would be to dissolve the zinc foil in HCl so we're able to titrate it..
then some how use back titration to find the mol mass and vol?
can someone help me with the method for finding the thickness asap?
thanks
