Ok, my partner and i are kinda stumped. heres the prob
We have the mass of an unknown at .525g its eithe NaHCO3 or KHCO3
After putting the crap through HCl then evaportaing the H2O we got it to .485g so now its either NaCl or KCl
and heres the givens
106g Na2 CO3 --> 97 g NaCl ~mass ratio 1:1
138g K2 C)3 --> KCl ~mass ratio 1:1
how can we determine whether the final substance is either KCl or NaCl
