The number of moles of helium that are in a 45.0-liter tank at 293 K and 15.0 atm is 28.1 Moles.
What are moles?
Moles is the measuring unit that measures the quantity of a substance. Moles is a SI unit.
Helium is the lightest gas, which is used in the tires of an airplane if it is filled in the balloons, the balloon flies in the sky.
Given the volume is 45.0 liter
The pressure is 15.0 atm.
The temperature is 293 K
To calculate the moles, we will use the formula of an ideal gas:
PV = n RT
R = .082057366 is the gas constant.
We have to calculate the n
Putting the values in the equation
15.0 x 45.0 = n x .082057366 x 293
n = 28.1 Moles.
Thus, the moles of helium is n = 28.1 Moles.
