Question

An alloy of a metal containing Al, Cu and Ge is to be produced as follows: 10g of Cu is mixed with 100 cm³ of Al. How many grams of Ge must be added to achieve 0.2 atom percent of Ge in the alloy?

Expert Solution

Step 1

From the given information:

Mass of copper in alloy = 10g

Molar mass of Copper = 63.6 g/mol

$N u m b e r o f a t o m s o f C u i n a l l o y = [\frac{m a s s}{m o l a r m a s s}] x A v o g a d r o N u m b e r N u m b e r o f a t o m s o f C u i n a l l o y = (\frac{10}{63.6}) x N A [D o n o t w r i t e t h e v a l u e o f N A]$

Number of atoms of Cu in alloy = 0.157 N_A
