Question

Density is a physical property of matter. Density does not change the identity of the substance; it just shows how close the particles of the substance are to each other.

The density of a substance also does NOT Change If you change the amount of the substance. One gram of gold has the same density as 10,000 grams of gold,
What is the density of gold if you have 96.9 grams of gold and it takes up 5mL of space?
17.9 g/mL
103.199174 g/ml
50,000 g/ml
19.32 g/mL

PLS HELP AND IF YOU CAN PLEASE HELP ME ON MORE, thanks!

Answer 1

The density of gold is 19. 38
`(g)/(mL)`

Step-by-step explanation:

Density is defined as the property that matter, whether solid, liquid or gas, has to compress in a given space. In other words, density is a quantity that allows you to measure the amount of mass in a given volume of a substance. So, the expression for the calculation of the density is the quotient between the mass of a body and the volume it occupies:

`density=(mass)/(volume)`

Density, according to the International System of Units, is usually expressed in kilogram per cubic meter (kg/m³) or gram per cubic centimeter (g/cm³). Although it can also be expressed in any other unit of mass by volume.

In this case:

• mass= 96.9 grams
• volume= 5 mL

Replacing:

`density=(96.9 g)/(5 mL)`

density=19. 38
`(g)/(mL)`

The density of gold is 19. 38
`(g)/(mL)`, that you could approximate the option 19. 32
`(g)/(mL)`
