Firstly, the density of any substance is represented by the mass (amount of matter) as divided by the volume(amount of space). According to external websites, the mass of a penny is 2.5 grams.However, the volume of a penny is .35cm to the power of 3 (due to the thickness of the penny being extremely minimal.Thus the amount of density is extremely little). Therefore, the density of a penny is 0.875 g/cm cubed (dimensional analysis).As for an invention that could be used, that is possible with the usage of a series of measurements that can both calculate mass and volume and directly allocate that to attain density
US participation in world war 1 affect the american civilian population in this following way : women had to get jobs and get more opportunities
Since the majority of the men have to go to the war, the business in the homeland was being taken care of by women
hope this helps
Use the following equation:
Given # of moles * molar mass (g) per mol = Mass (g)
This gives us 11.9 x <span> 51.9962 (g) per mol.
618.75 moles</span>
I took the test and can confirm that the answer is A.
It’s buildup of gas in your body lol
