Finding Mass of a Reactant
A chemist reacts sodium metal (Na) and chlorine gas (CI) to form salt according to the balanced chemical
equation: Na + Cl - NaCl.
If the chemist has 35.0 g Na, what mass of chlorine must he or she use to react completely with the
sodium?
Finally, solve (remember significant figures):
35.0 g Na
1 mol Na 1 mol CT 35.4 g CI
22.9 g Na 1 mol Na 1 mol CT
T = Ag CI
