Arectangular block of copper has a mass of 143.584 g and measures 5.05 cm by 2.55 cm by 1.25 cm. find the density of the copper block.

The density of copper block is, 8.92 g/mL

Explanation :  Given,

Length of copper block = 5.05 cm

Breadth of copper block = 2.55 cm

Height of copper block = 1.25 cm

To calculate the volume of copper block by using the formula of volume of cuboid, we use the equation:

where,

V = volume

l = length

b = breadth

h = height

Putting values in above equation, we get:

Conversion used :

Now we have to calculate the density of copper block.

Formula used :

Given:

Mass of copper block = 143.584 g

Volume of copper block = 16.1 mL

Now put all the given values in this formula, we get:

Therefore, the density of copper block is 8.92 g/mL

the answer is   c.) 1575 j.

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.
