How many moles of nitrogen are contained in a 250. mL flask at 300 kPa and 300 K
do you know how to solve it?
To find out how many moles of nitrogen are contained in the flask, we can use the Ideal Gas Law equation:
PV = nRT
Where:
P = pressure in Pascal (Pa)
V = volume in cubic meters (m^3)
n = number of moles
R = ideal gas constant (8.314 J/(mol·K))
T = temperature in Kelvin (K)
First, we need to convert the volume from milliliters (mL) to cubic meters (m^3):
Volume (V) = 250 mL = 250 x 10^-6 m^3
Next, we convert the pressure from kilopascals (kPa) to Pascals (Pa):
Pressure (P) = 300 kPa = 300,000 Pa
Now, we can substitute the values into the equation and solve for the number of moles (n):
n = PV / RT
n = (300,000 Pa) * (250 x 10^-6 m^3) / (8.314 J/(mol·K) * 300 K)
By performing the calculation, we can find the number of moles of nitrogen present in the flask.
Use PV = nRT
Yes I do but you need to learn how to do it.
Use PV = nRT
P = 300 kPa = (300/101.325) atm = ?
V = 250 mL = 0.250 L
R = 0.08205 L*atm/mole*K
T= 300 K
n = ?
Plug in the numbers and solve for n = number of moles.
