Answer : The minimum amount of 6.9 M
needed is, 2.0 L
Explanation :
The given chemical reaction is:

First we have to calculate the moles of 

Molar mass of
= 2 g/mol

Now we have to calculate the moles of 
From the balanced chemical reaction we conclude that,
As, 3 moles of
produced from 3 moles of 
So, 13.9 moles of
produced from 13.9 moles of 
Now we have to calculate the mass of 



Thus, the minimum amount of 6.9 M
needed is, 2.0 L
