steps to show how many pascals and atmospheres is 640 mmhg

Answer 1

First, we need an equation for converting mmHg to Pascal:

Pa/133.32 = mmHg

Because we are given mmHg, we would solve for Pa. Rearranging the equation gives:

Pa = 640 mmHg x 133.32 = 85324.8 Pascals

For atmospheres, or atm, we use the conversion factor of 1 mmHg = 0.00131579. Now we just use dimensional analysis:

640 mmHg (0.00131579 atm/ 1 mmHg) = 0.842 atm
