Answer:
Explanation:
The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. ... (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.) Mass. Although it is very small, the nucleus is massive compared to the rest of the atom.
Answer: 1169.298 L
Explanation: In order to go from grams to liters, you must find the moles first using the molar mass, 62.068 g/mol (found via google search). I will assume the ethylene glycol is in gas form so we can use the 22.4 L per mol conversion.
Using dimensional analysis, starting with the kg, we must convert to grams, then moles, then liters.
![\frac{3.24 kg}{} * \frac{1000g}{1 kg} * \frac{1 mol}{62.068 g} * \frac{22.4 L}{1 mol}](https://tex.z-dn.net/?f=%5Cfrac%7B3.24%20kg%7D%7B%7D%20%2A%20%5Cfrac%7B1000g%7D%7B1%20kg%7D%20%20%2A%20%5Cfrac%7B1%20mol%7D%7B62.068%20g%7D%20%2A%20%5Cfrac%7B22.4%20L%7D%7B1%20mol%7D)
Multiply the top individually, then the bottom individually.
![\frac{72576}{62.068}](https://tex.z-dn.net/?f=%5Cfrac%7B72576%7D%7B62.068%7D)
Divide out.
![= 1169.298 L](https://tex.z-dn.net/?f=%3D%201169.298%20L)
In the end, we get 1169.298 L of ethylene glycol.
There is a lot of water on earth. If oxygen was very soluble in water, the oceans would absorb and hold the oxygen of the atmosphere and there would be none left for plants and animals.
Hope this help you!!
Answer:
volume=0.4ml
Explanation:
use the equation
n=c×v. first make v become the subject of the formula by dividing c on both sides of the equation
v=n/c
v=0.100÷2.5×10^-2
v=4×10^-4
v=0.0004L
now convert 0.0004L to ml by multiplying 0.0004 with 1000 to get 0.4ml
therefore the volume in ml is 0.4ml
