What is the volume (in dm3 of 1 mole of oxygen at 5 mpa and 200 k?

The volume of oxygen gas is

Explanation:

To calculate the volume of the gas, we use the equation given by ideal gas equation:

where,

P = pressure of the gas = 5 MPa = 5000 kPa   (Conversion factor: 1 MPa = 1000 kPa)

V = Volume of gas = 3.34 L

n = number of moles of oxygen gas = 1 mole

R = Gas constant =

T = Temperature of the gas = 200 K

Putting values in above equation, we get:

Hence, the volume of oxygen gas is

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

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
