Indicate the si base units or derived units that are appropriate for the following measurements:
(a) the length of a marathon race(26 miles 385 yards)
(b) the mass of an automobile
(c) the volume of a swimming pool
(d) the speed of an airplane
(e) the density of gold
(f) the area of a football field
(g) the maximum temperature at the south pole on april 1,1913

The units of SI: meter, kilogram, second, Kelvin

Explanation:

(a) The length of a marathon race: meter (m)

(b) The mass of an automobile : kilogram (kg)

(c) The volume of a swimming pool : cubic meter (m^3)

(d) The speed of an airplane : (m/s)

(e) The density of gold : (kg/m^3)

(f) The area of a football field : square meter (m^2)

(g) The maximum temperature at the South Pole on April 1,1913: Kelvin (K)

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.

c. is the answer
