HELP WILL AWARD BRAINLIST! While sorting through a pile of old Petri dishes, Alexander Fleming noticed that the mold in one of the dishes prevented bacteria from growing there. He decided to study the mold. Years later, other scientists used the active compound in this mold to develop the first antibiotic, penicillin. Which statement describes Alexander Fleming's scientific discovery?

He made a discovery that disproved all other theories.

He made a discovery by working with a group of scientists.

He made a discovery by carefully following and repeating a procedure.

He made a discovery without using all the steps of the scientific method.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

im pretty sure its b
