10.5 g / 22.98977 = 0.457 moles Na

to get moles of chlorine you have to give me the molarity.

May be it means at STP

in this case

n = pV / RT = 1 x 18.6 / 0.0821 x 273 = 0.830 moles Cl2

2 Na + Cl2 >> 2NaCl

the ratio is 2 : 1 so Na is the limiting reactant

we get 0.457 moles NaCl

0.457 x 58.44 g/mol = 26.7 g
