Answer:
y = 5.5
Step-by-step explanation:
The total distance between the lines j and l is 10.
The total distance between the lines k and l is 9.
To find the distance between the lines j and k we can use the given information.
10 (distance between j and l) - 9 (distance between k and l) = 1 (the distance between the lines j and k).
So the distance between lines j and k is 1.
In the given picture the distance is shown as 2y-10.
This means 2y - 10 = 1
Now we need to solve this equation to find y.
2y - 10 = 1
2y = 1 + 10
2y = 11
y = 11/2
y = 5.5
(NOTE: We are not including 4 in the process of finding the value of y because this particular line is not similar to the line where y is )
The volume of the ethanol inside the tube can be obtained by dividing the mass of ethanol by the density. The volume is equal to 15.03 ml or 15.03 cm3. The volume of the tube is equal to pi d^2/4 * h where h is 15 cm. From this formula, the diameter is equal to 1.13 cm.
