Explanation:
earlier music used trills while later styles would use vibrato.
To allow for equations and problems in chemistry to be as precise as possible. When experiments are conducted, and even if the number is the slightest bit off, the problem or experiment could be impacted very negatively. It allows for complete accuracy to ensure nothing goes wrong, since chemistry is very touchy and risky when dealing with extremely unsafe elements.
Density = Mass / Volume
Input the values in their respective places and then use algebra to solve for volume.
Hope that helps.
