1.what solvent would you use to determine the density of magnesium nitrate?
im totally have no idea..
2. do know how to convert your densities to kg/L and comapre these wiht values wiht those in g/mL.?

3. if air bubbles were trapped in your solid beneath the liquid level in your density determination, what error would result in the volume measurement, and what would be the effect of this error on the calculated density?

4. a liquid that has a density of 0.80 + 0.01 g/mL is insoluble in cyclohexane. what is the liquid?

2. kg/L and g/mL are the same. 0.001kg/0.001L = 1g/1mL.

3. since gases have a conc. of 24L per mole, such a small air bubble will have a very lowwww mole count. in that case, the weigh can be taken to be neglible.
