Answer:
The balanced chemical reaction is given as:
Explanation:
When aqueous ferric nitrate is allowed to react with aqueous lithium hydroxide it gives solid precipitate of ferric hydroxide and aqueous solution of lithium nitrate. The balanced chemical reaction is given as:
According to reaction , 1 mole of ferric nitrate reacts 3 moles of lithium hydroxide to give 1 mole of ferric hydroxide and 3 moles of lithium nitrate.
C₀=2 mol/l
c₁=0.400 mol/l
v₁=100.0 ml = 0.1 l
c₁v₁=c₀v₀
v₀=c₁v₁/c₀
v(H₂O)=v₁-v₀
v₀=0.1*0.400/2=0.02 l = 20 ml
v(H₂O)=100 - 20 = 80 ml
It is necessary to mix 20 ml of the feed solution and 80 ml of water.
1L of 0.5M HCl contains 0.5mol of HCl which can react.
This can be found by the fact that
molarity is defined as the number of moles of a substance per Liter of solution. That means that 0.5M of HCl can be thought of as 0.5moles of HCl per liter of solution.
In general to find the number of moles of substance in a solution using the molarity all you do is multiply the molarity by the volume of the solution (in liters).
I hope this helps. Let me know if anything is unclear.
