Density

Oh Donnieboy...

Welcome to A2K.

Your question sounds suspiciously like homework. We are a helpful bunch here, but we don't like to do other people work for them. If you need it we will help you understand. But it doesn't do anyone any good for us to give you answers. It only contributes to the underwhelming science ignorance that many of us rant about.

Anyway this question needs more information (and I imagine this information is on the worksheet.) There are an infinite number of answers to this question.

Give us more information and what you are having trouble understanding and we will walk you through it.

Ocean water has about that density. Other salts such as magnesium sulphate, Sodium bisulphate, and lead nitrate can likely be dissolved in water to produce that density. Neil
