Science Buddies: "Ask an Expert"

PLEASE HELP ASAP!

We are working on the 5th grade experiment, “How Salty Does the Sea Need to be for an Egg to Float?”
Please explain in DETAIL how to calculate the relative and absolute salt concentrations.
My son has not had chemistry yet and is not familiar with moles, milimoles, etc.
I have searched previous posts on the topics but did NOT find them helpful.
Thanks!
