Tan2(∅) ≡ 2tan(∅) / (1 - tan²∅)

Thus,
2tan(∅) / (1 - tan²(∅)) + tan(∅) = 0
2tan(∅) / (1 - tan²(∅)) = -tan(∅)
1 - tan²(∅) = -2
tan²(∅) = 3
∅ = tan⁻¹(√3)
∅ = 4nπ/3

What volume of a 0.50 m mgso4 solution will be needed to prepare 100.0 ml of a 0.20 m mgso4 solution?
enyata [817]
The formula is given by Molarity of mgso4 required for the titration * Volume of mgso4 for the titration = Molarity of mgso4 used to make the solution * Volume of mgso4 used to make the solution. 
So we have 0.5 * Volume of mgso4 = 100 * 0.2 
So Volume of mgso4 = (100 * 0.2)/ 0.5 
Volume = 20/0.5 = 40ml = 40 * 10^(-3)
