Answer:
197 grams
Explanation:
Without taking into account the number of sig figs you have for your values, you can say that the answer will once again be
197 g of aluminium bromide.
(I hope this is right)
Volume has the same relationship with the number of particles than the pressure.
You can see it in the ideal gas equation: PV = nRT
As much as V and P are proportional to n.
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
