1 mm Hg pressure is the pressure due to 1 mm height of mercury

so it is given as

P = \rho g h

P = 1 * 10^{-3} * 13700 * 9.8 = 134.26 Pa

now we know that pressure is

P = 405 kPa

P = 405 * 10^3 Pa

so in mm Hg this pressure is

P = \frac{405 * 10^3 }{134.26} = 3016.5 mm Hg

so pressure in millimeter Hg will be 3016.5 mm Hg

A sample of a gas has a volume of 639 cm3 when the pressure is 75.9 kPa. What is the volume of the gas when the pressure is incr
const2013 [10]

Answer:

388 cm^3

Explanation:

For this problem, we can use Boyle's law, which states that for a gas at constant temperature, the product between pressure and volume remains constant:

pV=const.

which can also be rewritten as

p_1 V_1 = p_2 V_2

In our case, we have:

p_1 = 75.9 kPa is the initial pressure

V_1 = 639 cm^3 is the initial volume

p_2 = 125 kPa is the final pressure

Solving for V2, we find the final volume:

v_2 = \frac{p_1 V_1}{p_2}=\frac{(75.9)(639)}{125}=388 cm^3
