Answer:
<h3>The answer is 200 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 150 g
density = 0.75 g/cm³
We have
We have the final answer as
<h3>200 cm³</h3>

Answer: 0 neutrons
Explanation:
to find neutrons you subtract the atomic number from the Atomic mass. The atomic mass is 1. The atomic number is 1. So 1-1=0 making the neutrons in a hydrogen molecule 0.
Answer:
<h2>69.3 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
volume = 55 mL
density = 1.26 g/mL
mass = 1.26 × 55 = 69.3 g
We have the final answer as
<h3>69.3 g</h3>

Answer:
COMMENSALISM
Explanation:
Commensalism refers to the relationship that exists between two different organism that belong to different species.
