What is the pressure in atmosphers if the barometer reading is `688 mm Hg`?

A

`0.905 atm`

B

`0.986 atm`

C

`1 atm`

D

`0.876 atm`

Text Solution

Verified by Experts

The correct Answer is:
A
Since `1 atm = 760 mm Hg` , the pressure in atmospheres is calculated as follows:
`Pressure = 688 mm Hg xx (1 atm)/(760 mm Hg)`
` = 0.905 atm`
