Answer:
13.5%
Explanation:
To answer this you need to understand that percentage error can never be negative as we use absolute value in the equation
To get molar/atomic mass = mass/moles
=0.3681g/(6.514×10^-3)moles
=56.509g/moles
percentage error = (65.38-56.509)/65.38 ×100
=13.56% (this is what I'm getting without rounding off your question wasn't specific on how many d.p to use)

The equation will be balanced when the coefficient 2 is placed in front of NaNO3.
The principle that governs the balancing of reaction equations is that the number of atoms of each element on both sides of the reaction equation must be the same.
Let us consider the reaction; Na2S + Zn(NO3)2 -------> ZnS + NaNO3, the equation will be balanced when the coefficient 2 is placed in front of NaNO3.
