Assuming a stock concentration of 0.075 mM fluorescein, calculate the volume necessary to make 100 mL of a 0.029 microM fluorescein standard. The volumes will be fairly small and you'll use an eppendorf pipette to do the transfer. Report your answer as a whole number in microliter

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
