The volume of a gas at 99.0 kPa is 300.0 mL. If the pressure is increased to 188
kPa, what will be the new volume?

158.0 mL

Explanation:

We can solve this problem by using Boyle's law, which states that:

"For a fixed mass of a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

where

p is the pressure of the gas

V is its volume

The equation can be rewritten as

where in this problem:

is the initial pressure

is the initial volume

is the final pressure

Solving for V2, we find the final volume:

mL

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
