Detail is given below.

Explanation:

Given data:

Mass of enzyme = 32 g

Volume of water = 42.50 mL

Volume of water+ enzyme = 48.0 mL

Density of enzyme = ?

Solution:

Density is equal to the mass divided by volume.

First of all we will calculate the volume of enzyme.

Volume of enzyme = (volume of water+ enzyme ) - Volume of water

Volume of enzyme = 48.0 mL - 42.50 mL

Volume of enzyme =  5.5 mL

Density of enzyme:

d = 32 g/  5.5 mL

d = 5.8 g/mL

2)

Given data:

Mass of cup = 14 g

Volume of cup = ?

Density of cup = 2 g/cm³

Solution:

Density is equal to the mass divided by volume.

Formula:

d = m/v

2 g/cm³  = 14 g/  v

v = 14 g/2 g/cm³

v = 7 cm³

3) What are the four ways to measure matter?

weight, mass, volume, density

4) Given data:

Mass of rock = 18.5 g

volume of rock = 3cm³

density of rock = ?

Solution:

Formula:

d = m/v

d  = 18.5 g/ 3cm³

v = 6.16 g/cm³

5)

Given data:

mass = 6g

density = 8 g/cm³

missing value = ?

Solution:

d = m/v

8 g/cm³ = 6g / v

v = 6g/8 g/cm³

v = 0.75cm³

6)

Given data:

Volume of liquid in cylinder = 48 mL

Volume of toy car and liquid = 52 mL

Volume of car = ?

Solution:

Volume of car = volume of of toy car and liquid - Volume of liquid in cylinder

Now we will put the values.

Volume of car = 52 mL - 48 mL

Volume of car = 4 mL
