2x 6.022x10^23= 1.204x10^24
Answer: 4000000000
because 20X200000000=4000000000
Today scientist don't believe there's life in this solar system but there is proof of living things that once used to live on mars. there might be life in our universe and other galaxies.
Explanation:
Answer:

Explanation:
Hello,
In this case, for this heat transfer process in which the heat lost by the hot platinum is gained by the cold deuterium oxide based on the equation:

We can represent the heats in terms of mass, heat capacities and temperatures:

Thus, we solve for the mass of platinum:

Next, by using the density of platinum we compute the volume:

Which computed in terms of the edge length is:

Therefore, the edge length turns out:
![a=\sqrt[3]{180cm^3}\\ \\a=5.65cm](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B3%5D%7B180cm%5E3%7D%5C%5C%20%5C%5Ca%3D5.65cm)
Best regards.
I think the most appropriate answer is: the solvent being used in the experiment
<span>To correct for any light absorption not originating from the solute you will need to calibrate the tools with a solution that most similar to the sample.
Blank covete or standard solution can be used, but it was not ideal. By using the solvent as calibration, you can remove the reading from the solvent so your result only comes from the sample.
