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.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
