I think you mean sodium and not sodium hydroxide

First, you need to set up the reaction equation:

2 Na + Cl2 → 2 NaCl

you know that there is ratio 2 : 1

Then you calculate the amount (n) of NaCl if m = 10g

n = m/M

then you recreate the amount of fabric once the ratio 2

and then have the amount of substance from your natium with the formula:

and now have the desired mass

*n(Na)≅23 g/mol; n(Cl)≅35 g/mol
