2Na(s)+Cl 2 (g) 2NaCl(s)
A chemist determines that the mass of an empty flask with a stopper is 156.1870g. After filling the stoppered flask with chlorine gas (Cl2 ) it’s mass is 158.1743. The chemist introduces 0.3870g of elemental sodium (Na) into the flask, causing a violent reaction and creating NaCl. All of the solid sodium is used up by the reaction. The chemist collects the unreacted chlorine gas and determines its mass to be 0.7962 g.
1. How many moles of elemental sodium were used in the reaction?
2. What is the mass of chlorine gas used in the reaction?
3. How many moles of chlorine were used in the reaction?
4. What is the empirical formula of sodium chloride based on the experimental data?
5. Was the empirical formula you obtained correct using the chemists data correct? Why?
