Question

The atmospheric pressure on the surface of Venus is 6.84X10^4. Calculate the atmospheric pressure in atm and torr. Round each of your answers to 3 significant digits.

Answer 1

0.675 atm

513 Torr

Step-by-step explanation:

Given is that, the atmospheric pressure on the surface of Venus is

6.84 X 10⁴ Pa.

1 atm (atmospheric pressure) is equal to 101325 pascal (Pa).

To convert divide the pressure value by 101325.

Pressure in atm =
`(6.84 * 10^(4) )/(101325)`

= 0.675055 atm

Rounding it off to 3 significant digits: 0.675 atm

Now, one Torr is 133.322 Pa. For conversion, divide the pressure value by 133.322.

Pressure in Torr =
`(6.84 * 10^(4) )/(133.322)`

=513.04219 Torr

Rounding it off to 3 significant digits: 513 Torr
