Answer:
15 moles.
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Clearly, since carbon and oxygen are in a 1:1 molar ratio, 15 moles of carbon will completely react with 15 moles of oxygen, therefore 15 moles of oxygen remain as leftovers. In such a way, since carbon and carbon dioxide are also in a 1:1 molar ratio, the theoretical yield of carbon dioxide is 15 moles based on the stoichiometry:
Best regards.
Answer:
The object with the greatest density
Explanation:
The object that will have the greatest mass from the given choices is the one with greatest density.
Density is the mass per unit volume of a substance;
Density =
We can see that density is directly proportional to the mass and inversely proportional to the volume.
The more the mass and the lesser the volume, the higher the density.
So, since the volume is the same, and mass is directly proportional to density, the object having the highest density will have the greatest mass.
Answer:
The answer is
<h2>1.87 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 79.6 g
volume = 42.5 mL
The density of the liquid is
We have the final answer as
1.87 g/mL
Hope this helps you
