Which of the following is not a step in the scientific method? a. research b. existing sources report results c. receive corroboration from the field d. formulate a hypothesis

c. receive corroboration from the field

Explanation:

Following options are a step in scientific methods

a. Research

b. existing source report results

d. Formulate a hypothesis

Therefore only option does not come under scientific method is

c. receive corroboration from the field

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
