Answer:
The density of the final mixture is 1.012 g/cm³.
Step-by-step explanation:
To calculate the density of the final mixture we need to know the mass of each solution used is. We will also need to convert the volumes from litres to cm³, to do that we can just multiply 1000.
For the ethanol:
For the propylene:
So the mass in the final mix is the sum of both:
Therefore the density is:
Answer:
x = 6
Step-by-step explanation:
(3√2)² = 18
using the Pythagorean theorem:
x² = 18 + 18 = 36
x = √36 = 6
Answer: x = 0; x=10
Step-by-step explanation:
