Answer : The pressure in atmospheres, bars and kilopascals is, 0.276 atm, 0.279 bar and 27.99 kPa respectively.
Explanation :
As we are given that the barometric pressure is, 210 mmHg.
Now we have determine the pressure in atmospheres, bars and kilopascals.
Conversions used for pressure :
1 atm = 760 mmHg
1 atm = 101.325 kilopascals (kPa)
1 atm = 1.01325 bar
First we have to determine the value of pressure in terms of atmosphere.
As, 760 mmHg = 1 atm
So, 210 mmHg = [tex]\frac{210mmHg}{760mmHg}\times 1atm[/tex]
= 0.276 atm
Now we have to determine the value of pressure in terms of bars.
As, 760 mmHg = 1.01325 bar
So, 210 mmHg = [tex]\frac{210mmHg}{760mmHg}\times 1.01325bar[/tex]
= 0.279 bar
Now we have to determine the value of pressure in terms of kilopascals.
As, 760 mmHg = 101.325 kPa
So, 210 mmHg = [tex]\frac{210mmHg}{760mmHg}\times 101.325kPa[/tex]
= 27.99 kPa
Therefore, the pressure in atmospheres, bars and kilopascals is, 0.276 atm, 0.279 bar and 27.99 kPa respectively.
