5200mL </span>→ 520 cL → 52dL →<span>
5.2L</span><span>Example:
If
1L ------ 1000mL
x -------- 5200mL
1000x = 5200
</span>

<span>x =
5,2</span>
Therefore:
<span>
52L >
5200mL or 5.2L (True)

In order to construct this equation, we will use the variables:
V to represent mixture volume (40 ml)
C to represent mixture concentration (0.32)
v₁ to represent volume of first solution (40 / 4 = 10 ml)
c₁ to represent concentration of first solution (0.2)
v₂ to represent the volume of the second solution (40 * 3/4 = 30 ml)
c₂ to represent the concentration of the second solution
We know that the total amount of substance, product of the volume and concentration, in the final solution is equal to the individual amounts in the two given solutions. Thus:
VC = v₁c₁ + v₂c₂
40(0.32) = 10(0.2) + 30c
F(1)=4(1+1+7)-2(1)+8-4
f(1)=36+2
f(1)=38
f(2)=4(2+2+7)-2(2)+8-4
f(2)=44
