Question  options:

0 deg C and 1 kPa.


0 deg C and 1 atm.


100 deg C and 760 mm Hg.

Answer 1

The STP is Standard temperature and pressure.

Standard temperature is defined as zero degrees Celsius (0° C)

Standard pressure supports 760 millimeters in a mercurial barometer (760 mmHg)

we have that
760 mmHg= 1 atm

therefore
the answer is 0 deg C and 1 atm.
