The pressure is recorded as 738 mmHg.Convert this measurement to atmosphere (atm)
garri49 [273]
As we know that 760 mmHg is equal to 1 atm.

So,
If 760 mmHg is equal to   =   1 atm
Then
738 mmHg will be equal to   =   X atm

Solving for X,
                                X   =   (738 mmHg × 1 atm) ÷ 760 mmHg

                                X   =   0.971 atm

Result:
           738 mmHg
is equal to 0.971 atm.
