Question

The atmospheric pressure in denver, co is 633 mmhg. what is this pressure in atm?

Answer 1

1 atm of pressure corresponds to 760 mmHg. Therefore, we can set a simple proportion to find how many atmospheres of pressure correspond to 633 mmHg, in the following way:
$1 atm : 760 mmHg = x : 633 mmHg$
And if we solve this proportion, we find the pressure in atmospheres:
$x= \frac{1 atm \cdot 633 mmHg}{760 mmHg}=0.83 atm$
