How many atoms of chlorine does a 1.3 kg sample of barium chloride
contain?


What is the formula for a hydrate which consists of 2.73 g of CoCl2 and
2.27 g of water?
 
its really easy....
im not telling u the answer so you can actually do the work and learn!
get atomic # of CL and divide it with 1.3 Kg and the other step is pretty obvious -.-

for second one. start with CoCl2 atomic # first and divide it with 2.27g of H2O the rest is pretty clear... next you just multiply is with 2.73g

EASY PEASY!
