Thank you for the opportunity to help you with your question!

first write balanced equation as follows  :  2Na + S → Na2 S

45.3g Na &  105g  Sulpher  than  Na2S = m=?

we know that

23g/mol na and  32.07g/mol  sulpher gives 78.05 gm moles Na2S (23*2 +32.05 =78.05g/mol  of Na2S)

moles Na available= 45.3 g/23 g/mole=1.96mole

1.96 * (1 mole of Na2S)  / (2 mole of Na) =  0.98 mole of Na2S

(0.98 mol of Na2S) X 78.05 g/mol     here moles  get cancelled with each other hence we get

 76.48 g of Na2S   (Answer)
