These days, scientists all over the world use a standard system of measurements. It's the SI or metric system.
What about scientists in the United States, Liberia, and Burma ? These three countries are the only ones in the world that haven't adopted the metric system. What do THEY do ?Easy. When scientists in those countries are off work, they use the inches, yards, feet, quarts, miles and gallons that everybody around them is using. But when they go to work, they use the same metric system that everyone else in the world is using.

IF THE FIRST ONE DOESN'T WORK TRY THE SECOND
1. They use the same measuring system (metric)2. Clearly and properly collect and record data, recording the procedure and results3. Releasing the data into the public, letting everyone have access to it

Answer:
All of the above
Explanation:
Panthers, pumas, and mountain lions are all the same animal. Just different names. So, all of these would be correct.
Moles = weight in grams / molecular weight.
So I would divide the "grams of barium" by its molecular weight (which is 137.3) to get "moles of barium". :)
Answer:
radiation
Explanation:
radiation is the transfer of heat energy through space by electromagnetic radiation
Answer:
M = 3.69 M.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the molar concentration of the 1.29 moles of KCl in 350 mL of solution by recalling the mathematical definition of molarity as the division of the moles by the volume in liters, in this case 0.350 L; thus, we proceed as follows:
Which gives molar units, M, or just mol/L.
