Convert 0.600 atm of pressure to its equivalent in millimeters of mercury. express the pressure numerically in millimeters of mercury.

Answer is 456 mmHg.

Explanation;

This is a simple unit conversion problem.

1 atm = 760 mmHg

Hence,

0.600 atm = (760 mmHg / 1 atm) x 0.600 atm

                 = 456 mmHg

Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.

The relationships among those units as follows

1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
