Answer:
0.16mole
Explanation:
To solve this problem, we are going to assume that the number of moles of carbon to be determined is that at STP, standard temperature and pressure.
The number of moles of a substance at STP is given as;
Number of moles =
Given volume = 3.5L
Now, insert the parameters;
Number of moles = = 0.16mole
Answer:
<h3>The answer is 1.59 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 = 12.5 g
density = 7.87 g/cm³
We have
We have the final answer as
<h3>1.59 cm³</h3>Hope this helps you
