Answer:
The pressure in mmHg is 59.
Explanation:
Given data:
Pressure of air inside balloon = 0.78 atm
Pressure in mmHg = ?
Solution:
mmHg:
mmHg is referred as manometric unit of pressure. It is define as the pressure exerted by mercury column at height of one millimeter.
Symbol:
"mmHg"
Atmosphere (atm)
atm is unit of pressure. It is used as a standard unit. It is equal to the 101325 Pa.
1 atm = 760 mmHg
Inorder to convert the atm into mmHg we will multiply the given atm value with 760.
0.78 atm × 760 mmHg / 1 atm = 592.8 mmHg
59 mmHg or 59
