Question

the atmospheric pressure on the surface of venus is 90.0 atm. calculate the atmospheric pressure in mmhg and torr. round each of your answers to 3 significant digits. mmhg torr

Explanation:

Step1: Convert atm to mmHg

We know that \(1\ atm = 760\ mmHg\).
So, for \(90.0\ atm\), the pressure in \(mmHg\) is \(90.0\times760\).

$$90.0\times760=(9\times10)\times(7.6\times10^{2})=(9\times7.6)\times(10\times10^{2}) = 684\times10^{3}=6.84\times 10^{4}\ mmHg$$

Step2: Convert atm to torr

Since \(1\ atm=760\ torr\) (because \(1\ mmHg = 1\ torr\)).
For \(90.0\ atm\), the pressure in torr is \(90.0\times760\).

$$90.0\times760=(9\times10)\times(7.6\times10^{2})=(9\times7.6)\times(10\times10^{2})=684\times10^{3} = 6.84\times 10^{4}\ torr$$

Answer:

\(6.84\times 10^{4}\ mmHg\), \(6.84\times 10^{4}\ torr\)
