Answer:
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
Answer:
Science is a process of observation and experimentation
The answer is <span>D. The type of plant that grew near a river.
A clastic rock is composed of fragments of rock and geological detritus and smaller grains of rock. Its composition is determined by source rock composition and crystals. It can be noticed that the type of plant that grew near a river has nothing to do with its composition.</span>
