The grams of sodium chloride that will be made is 292.5 g
<u><em>calculation</em></u>
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
Area measured in squares (or square units). We can count the squares or we can take the length and the width multiplication. The rectangle above has an area of 15 square units.
N203 is the answer, if i am wrong im sorry!
