6. what is the density of an irregular shaped object that displaces 15 ml of water and has a mass of 12 grams? would this object float or sink if placed in water? explain.

Volume of the object is equal to the volume of water displaced by it = 15 ml

The mass of the object is given as 12 g

Density of a substance is the amount of that substance per unit volume

i.e. Density = Mass/volume = 12 g/15 ml = 0.8 g/ml

The density of water is 1 g/ml. If the density of an object exceeds that of water, then it will sink otherwise it will float.

Here, the density of the object (0.8 g/ml) is lower than that of water, hence it will float if placed in water.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
