Answer:
113406825 N/m²
Explanation:
The pressure at depth of 11,000 m can be calculated by:
Pressure = Atmospheric pressure + Pressure due to height
Atmospheric pressure = 101325 N/m²
Also,
Where,
is the density of water (
)
g is the gravitational acceleration = 9.81 m/s²
h = 11,000 m
Pressure due to height = 113305500 N/m²
<u>Pressure = Atmospheric pressure + Pressure due to height = 101325 N/m² + 113305500 N/m² = 113406825 N/m²</u>

Alchemy was based more on experimentation and had little basis in science. Chemistry utilizes both experimentation and scientific practices. Modern chemistry basically relies on scientific theories and experimental results, but the alchemy was a blend of myths, religion, magic, astrology, philosophy, and spirituality.
