African Americans in the Civil War faced many problems. They were usually treated differently and had restricted roles. This doesn't mean that they didn't fight just as bravely as the other solders. Many of them died nobly for their cause.
1 grain of sugar contains about 600 quadrillion molecules of glucose which can be used to make about 18 quintillion molecules of ATP
It would take about 77 quintillion molecules of glucose to make 1 second of atp and it would take around 2.310 sextillion molecules of glucose to make 30 sec of atp and somewhere around 77 quintillion grains of sugar to store around 30 seconds of atp
30 molecules of atp are made with 1 molecule of glucose 10 glucose molecules make 300 atp
(the number of glucose molecules times 30 equals the number of ATP molecules.)
Divide the number of molecules of ATP needed by 30.
7.7 x 10^19 (77 quintillion)
I'm not sure if you made a typo or not but in the current context I can only see negligible being relevant.
a) the fertile soil led to food surpluses, which supported a larger group of people
