Explanation:
This is the only answer I can come up with.
The only metalloid located in the sixth period of the periodic table is Astatine. Others are located in previous periods.
Mass of Copper : 63.5 g
<h3>Further explanation</h3>
Given
Reaction
Cu(s)+2AgNO₃ (aq) ⇒Cu(NO₃)₂ (aq)+2Ag(s)
Required
Mass of Copper
Solution
mol of Silver nitrate :
= M x V
= 2 mol/L x 0.5 L
= 1
From the equation, mol ratio of Cu : AgNO₃ = 1 : 2, so mol Cu = 1
Mass of Cu(Ar=63.5 g/mol) :
= mol x Ar
= 1 x 63.5
= 63.5 g
