Answer:
The pressure of 0.5 mole of nitrogen gas=
Given:
Moles of nitrogen gas=0.5mole
Volume of nitrogen gas=5L
Temperature of nitrogen gas=203K
To Find:
Pressure of 0.5g mole of nitrogen gas
<u>Step by Step by Explanation:</u>
Formula used for calculating the pressure of a gas is achieved through ideal gas equation
According to Ideal Gas;
From this above equation, pressure can be calculated as
Where P=Pressure of the gas
N=number of moles=0.5moles
R=Gas constant
V=Volume of nitrogen gas in litres=5L
T=Temperature of nitrogen gas=203K
Substitute all the values in the above equation we get
Result:
Thus the pressure of 0.5 mole of nitrogen gas is <u></u><u>
</u>
Isotopes are atoms with different number of electrons
isotopes are very useful
for example isotope of uranium is used in atomic bombs and nuclear reactors radioactive isotopes are used to date ricks soils and archaeological objects.
isotopes have many uses that's why we study isotopes to know their uses
