The atomic mass of Ag is 107.87. The atomic mass of Cl is 35.45. The molecular mass of AgCl is therefore 143.32. 0.025 mols of AgCl were produced. This required .0125 mols of the original metal chloride since it has 2 chlorine atoms per molecule and AgCl only has one per molecule.
The molecular mass of mCl2 must be 127.2 in order for 1.59g of mCl2 to be .0125 mols. The molecular mass of m can be calculated by subtracting the molecular mass of 2 chlorine atoms

Answer:
0.50 g of Na Metal
Solution:
The equation for given reaction is as follow,
2 NaN₃ → 2 Na + 3 N₂
According to equation,
When,
67.2 L (3 mole) N₂ is produced along with = 46 g (2 mole) of Na Metal
So,
0.744 L N₂ produced will accompany = X g of Na Metal
Solving for X,
X = (0.744 L × 46 g) ÷ 67.2 L
X = 0.50 g of Na Metal

<h3>Further explanation
</h3>
Work is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
Force=F= 5 N
Distance=d=3 m
