Question

780. mm Hg to kPa,
I'm struggling to get the answer with the correct sig figs ;(

Answer 1

103.9 kPa

Step-by-step explanation:

It's more easy to convert mmHg to Pa and then /1000

Let's try the rule of three:

760 mmHg is 101325 Pa

780 mmHg (780 mmHg . 101325 Pa) / 760mmHg = 103991.4 Pa

1 kPa = 1000 Pa

103991.4 Pa / 1000 = 103.9 kPa
