Answer:
The body with 2.7 
has a larger volume
Explanation:
There is a missespelling in the question. The units of density cannot be g, they usually are
In order to answer this question, we need to use the formula of the density of a body:
For body A:
Mass (M) = 5.0 g
Density (D) = 2.7
2.7 = 5g * 1/V
V1 = 5g / (2.7 )
V1 = 1.85 
For Body B:
Mass (M) = 5.0 g
Density (D) = 8.4
8.4 = 5g * 1/V
V2 = 5g / (8.4 )
V2 = 0.59
So V1 is bigger than V2
16.25 ml NaOH was used for the titration.

Titration:</h3>
"The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration.
A titration is a method for figuring out the concentration of an unknown solution by using a solution with a known concentration. Until the reaction is finished, the titrant (the known solution) is typically added from a buret to a known volume of the analyte (the unknown solution).
0. 010 m NaOH is the titrant (in the buret).
The initial buret reading is 2. 45 ml
The final buret reading is 18. 70 ml
The volume of NaOH = 18.70ml - 2.45 ml
= 16.25 ml
Therefore, 16.25 ml NaOH was used for the titration.

H:O = 4:5;
(UO₂)₂ = 4 O atoms;
(PO₄)₂ = 8 O atoms:
8H₂O = 16 H atoms + 8 O atoms;
Total = 16 H atoms + 20 O atoms;
H:O = 16:20 = 4:5
