The testable question which will provide evidence that elements in the same group have similar properties is valency
<h3>What is the valency?</h3>
In essence, how many electrons are present in their outermost shell.
Valency and Groups in the periodic table, elements are arranged in order of their atomic numbers and hence, the periodic table is a systematic arrangement of elements in an array of vertical columns called Groups and horizontal arrays called Periods.
which of the following testable questions will provide evidence that elements in the same group have similar properties A. Valency B. Orbit C. Group D. Period
Since, the reactive capacities of elements is dependent on the number of electrons on its outermost shell, we can conclude on this note that, Elements in the same group have similar properties.

The formula to find moles is:
n = m / M
m stands for mass, which in this case m = 64.92g
M stands for molar mass. You would need to look at the periodic table for each element of AgNO3 and add them together to get M.
n = 64.92 / 107.9 + 14.01 + 3(16)
= 0.382084...
= 0.38 moles (2 d.p)
Hope this helped!
