Answer:
The cylindrical tube can hold 0.215 cubic decimeters of blood.
Explanation:
Diameter of the cylindrical tube = d = 4.5 cm
r = d/2 ,r = 2.25 cm
Height of the cylindrical tube = h = 13.5 cm
Volume of the cylinder = V =
The cylindrical tube can hold 0.215 cubic decimeters of blood.
Answer:
I’ll put the answer the comments if you can give the actual question
Explanation:
Oil water corn syrup and honey
The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
<h3>Determine hydronium ion concentration when pH = 7 </h3>
Given that :
pH = 8.0
Hydronium ion concentration = 1 * 10⁻⁸ mole/liter
Resolving the question
8.0 = 1 * 10⁻⁸ mole/liter
7.0 = x
therefore :
x = 7 ( 1 * 10⁻⁸ ) / 8.0
= 8.75 * 10⁻⁹ mole/liter
Hence we can conclude that The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
