Question

can you show all the steps

can you calculate mole of water ,mass of chlorine in sample, moles of chlorine, mole ration ,chlorine : copper in sample , formaula of degydrated sample and formula of hudrated sample using the data from page 1

26 Experiment 4 Determination of a Chemical Formula Moles of water moles Mass of chlorine in sample (by difference) Moles of chlorine moles Mole ratio, chlorine:copper in sample :1 Mole ratio, water.copper in hydrated sample :1 Formula of dehydrated sample (round to nearest integer) Formula of hydrated sample Experiment 4 Data and Calculations: Determination of a Chemical Formula Atomic masses: Copper (Cu) Chlorine (CI) g/ mol - g/ mol Hydrogen (H) g/ mol Oxygen (O) -g/ mol 31.9519 Mass of crucible 33.048 Mass of crucible and hydrated sample 1.096 Mass of bydrated sample 32.7019 Mass of crucible and dehydrated sample 0.75 Mass of dehydrated sample 0.4765 Mass of filter paper 0.8471 Mass of filter paper and copper 0.3706 Mass of copper 171.479 Moles of copper moles Mass of water evolved (continued on following page
