An object has 15 grams of atoms and displaces 2.5 mL of water when dropped into a cylinder. What is the objects density... HELP IM IN CLASS RN AND I NEED ANSWERS ASAP, grades are due in couple hours

6g/mL

Explanation:

The density, which is the mass per unit volume of an object, can be calculated using the formula;

D= m/v

Where; D = density (g/mL)

M = mass of substance (g)

V = volume (mL)

In this question, the object's mass = 15g, volume of water= 2.5 mL, d =?

Therefore,

Density = 15/2.5

Density = 6 g/mL

The object's density is 6g/mL

it is a solid
