How Salty does the Sea have to be for an egg to float?

[OrtizR]

Equation # 1

p= m/v for us p= m-292 grams of salt over v- .946 liters of water Basically- 1 cup of salt in 1 quart of water- STOCK

p= 309 or 308.6 = Is this grams per mililiter? Is this the density of the salty water- our stock-?

Next, Equation # 2

new concentration - Volume of stock/(volume of stock + volume of water)

Cups

#1- 3/4 cup stock
#2- 3/4 cup stock & 3/4 cup water- new mix 50% or 1/2 stock
#3- 3/4 cup water & new mix 3/4 cup stock from #2 - 25% or 1/4 stock
#4- 3/4 cup water & new mix 3/4 cup stock from #3 - 12.5% or 1/8 stock
#5- 3/4 water

so, do we divide the 309 by 2, 4 , and 8 for the densities-absolute solutions- for cups 2-4??????????
Is the relative solutions the percentages?????????

Please Help??????? Project due tomorrow!

Hello OrtizR:

It looks like you are well on your way to understanding this experiment.

I would like you to take a look at the units you are using for equation #1. As you have stated the your mass is in grams and your volume is in liters. Therefore, with p=m/v your units would be grams per liter. As p represents the density, this is the density of your stock.

Please let me know if you have any follow-up questions.
