Answer:
236.02 grams of Na is produced by 600g of NaCl.
Explanation:
NaCl --> Na+Cl-
to find the number of moles NaCl has, divide the grams over the molar mass which is 600/58.44
number of moles of nacl= 10.2 moles
then turn moles back to grams which is moles x molar mass
10.2 moles x 22.9 mass
= 236.02 grams
