Each cubic centimeter of gold has a mass of 19.3 g. a cube of gold measures 4.23 cm on each edge. (a) what is the volume of the cube? what is its mass?

The volume of the gold is  

The mass of gold is 19.3 g

The density of gold is

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of gold = 19.3 grams

To calculate the volume of cube, we use the equation:

where,

V = volume of cube

a = edge of cube

Volume of gold =

Putting values in above equation, we get:

Putting in the values we get:

Thus density of gold will be

1 a

2 d

3 a

4 c

explanation:

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
