54.936 grams of NaCl will be produced from 33.0 g of Na and 34.0 g of Cl.
Explanation:
Data given:
mass of Na = 33 grams
mass of = 24 grams
atomic mass of Na = 23 grams/moles
atomic mass of Cl = 70 grams/mole
mass of NaCl formed =?
atomic mass of NaCl = 58.44 gram/mole
balanced chemical reaction:
2Na + ⇒ 2NaCl
number of moles =
putting the values in the equation:
number of moles of Na =
= 0.69 moles
number of moles of chlorine gas =
= 0.47 moles
limiting reagent is chlorine gas in the reaction
from the balanced chemical reaction:
1 mole of chlorine gas reacts to form 2 moles of NaCl
then 0.47 moles of chlorine gas will form x moles
=
x = 0.94 moles of NaCl is formed.
mass = atomic mass x number of moles
mass = 58.44 x 0.94
= 54.936 grams of NaCl is produced.
