Answer:
114.7g
Explanation:
Given parameter:
Mass of Na = 45g
Unknown:
Mass of produced NaCl = ?
Solution:
The reaction equation is shown below;
2Na + Cl₂ → 2NaCl
Now, we solve from the known to the unknown. The known here is the mass of Na and it is sufficient to solve the problem;
Number of moles =
Molar mass of Na = 23g/mol
Number of moles = = 1.96moles
2 mole of Na produced 2 moles of NaCl
1.96 moles of Na will produce 1.96 moles of NaCl
Mass of NaCl = number of moles x molar mass
= 1.96 x [23 + 35.5]
= 114.7g
