Ar (g) is placed in a 3.80 L container at 320 K. The gas pressure is 0.496 atm.
nata0808 [166]

Answer:

PV=nRt

Therefore n(number of moles)=PV/RT

=>(0.49×3.80)/(0.08206×320)

Therefore Number of moles is = 0.071mols

Explanation: By using the Real gas equation..

PV=NRT .

We can solve for the number of moles of Ar by making N the subject..

Always make sure you pressure is In atm, your Volume is in Litres and temperature in degree Kelvin.

Also Recall the universal gas constant R used in this type of questions which is 0.08206.

Hence l, by making N the subject we get our answer as

Why are units used that are to express the densities of gases different from those used to express the densities of solids or li
aksik [14]
If the units for gases were the same as the units for numbers would be too small to be convenient.

For example, the density of iron is 7.87 g/cm³.

Using the same units, the density of hydrogen is 0.000 0899 g/cm³.

It is much more convenient to express the density in numbers that are easier to visualize: 0.0899 g/L, and that is still a small number.
