Included are my labs sheets, data I calculated, and a poor sketch of a graph at this stage. On page 52 would someone please help me to answer all the questions and the one pertaining to my graph?

I think that the problem is with the measurements and the formula used. In the formula Wi is given, while you are measuring the mass Wo of the object. Hence Wi should be written in terms of Wo.

Hence

As Wo is measured in Kg, which is the unit of mass to convert it into weight, we have to multiply it with g (acceleration due to gravity), which cancelled g from denominator.

As the volume is measured in terms of mass of the displaced water the volume of the object is given by V/w. As well as the density is required in Kg/cm3, the volume should be written as (V/)*106 cm3 = V*103 if V is in Kg and V if it is in gram. (Remember the density of water is 1 gm/cm3)

Hence the final farmula should be

Calculations:

Object Wo (Kg) V(gm)

Large Rectangle 0.249 92 2.707*10-3
Large Square 0.374 45 8.311*10-3
Cylinder 0.088 31 2.839*10-3

For the second set

Object Wo (Kg) V(gm) ...

The acceleration of a marble in a certain fluid is proportional to the speed of the marble squared and is given in SI units) by a=-3.00 v^2 for v greater than 0. If the marble enters this fluid with a speed of 1.20 m/s, how long will it take before the marble's speed is reduced to half of its initial value?

Hey I am about to do a lab to determine the amount of caffeine and sodium benzoate in soft drinks via HPLC. To prepare I had to answer a series of questions before the lab. I am confused on some of them and request your help. The questions are:
Why is it necessary to perform the HPLC separation at a pH of 3? How does the pH a
