Question

$1Pa$ of pressure is equal to:

• A. $7.5\times {10}^{-3}Torr$
• B. $7.5\times {10}^{3}Torr$
• C. $760Torr$
• D. $1Torr$

Answer 1

The correct option is A $7.5\times {10}^{-3}Torr$

Atmospheric pressure $=1atm=760torr=1.01\times {10}^{3}Pa$

$⟹1Pa=\frac{760}{1.01\times {10}^5}torr=7.5\times {10}^{-3}torr$
