The grams of sodium chloride that will be made is 292.5 g
calculation
2Na +Cl₂ → 2NaCl
step 1: calculate the moles of Na
moles = mass/molar mass
From periodic table the molar mass of Na = 23 g/mol
moles = 115 g/23 g /mol = 5 moles
Step 2 : use the mole ratio to determine the moles of NaCl
Na:NaCl is 2:2 = 1:1 therefore the moles of NaCl is also= 5 moles
Step 3: find the mass of NaCl
mass= moles x molar mass
The molar mass of NaCl = 23 + 35 .5 =58.5 g/mol
mass= 5 moles x 58.5 g/mol =292.5 g
