start with a balanced equation. Then, notice the ratio of moles Na to moles of NaCl.
MolesNaCl=Ratio*molesNa
then finally, convert the moles of NaCl to mass
MassNaCl=MolesNaCl*formulamassNaCl
where formula mass of NaCl is the atomic mass of Na plus the atomic mass of chlorine atom.
In my head, I get about 320grams of sodium chloride.
MolesNaCl=Ratio*molesNa
then finally, convert the moles of NaCl to mass
MassNaCl=MolesNaCl*formulamassNaCl
where formula mass of NaCl is the atomic mass of Na plus the atomic mass of chlorine atom.
