Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 100 g
volume = 20 mL
So we have
We have the final answer as
<h3>5.0 g/mL</h3>
Hope this helps you
Answer:
They are both polymers that are found in living cells.
Explanation:
Characteristic of matter that is not associated with its change in chemical composition.
Answer:
The mass of S that reacted is 0.642g
Explanation:
In this case we have
⇒ mass of crucible and cover, 25.429g
⇒ mass of crucible, cover, and Pb, 29.465g
⇒ mass of crucible, cover and commass of crucible and coverpound formed, 30.107g
The mass of Pb reacted = mass of crucible, cover, and Pb - mass of crucible and cover = 29.465 - 25.429 = 4.036g
The mass of compound formed = mass of crucible, cover and commass of crucible and coverpound formed - mass of crucible and cover = 30.107 - 25.429g = 4.678g
The mass of S reacted = Mass of compound formed - mass of Pb reacted = 4.678 -4.036 = 0.642g
The mass of S that reacted is 0.642g
