Answer:
17.94 annd 27.69 respectively.
Explanation:
Na(s) + Cl(g) n` NaCl(s)
mass of NaCl = 45.6 g
Mr of NaCl = 23 + 35.5
= 58.5g/mol
mole of NaCl = mass/Mr
= 45.6/58.5
= 0.78 moles
From the equation;
1 mole of NaCl = 1 mole of Na = 1 mole of Cl
hence 0.78 mol of NaCl = 0.78 mol of Na = 0.78 mol of Cl.
mass of Na = 0.78 × 23
= 17.94 grams
mass of Cl = 0.78 × 35.5
= 27.69 grams
