Answer:

1atm = 1.013 × 10^5 pascals

Explanation:

barometer is used to measure atmospheric pressure because it is the pressure exerted by atmosphere at certain altitude and as height in barometer column of mercury increases the atm pressure is more in that place if height is less then atm pressure is also less.

  • hence we write Atm pressure = rho*g*h
