Question
Part A: A gas system has pressure, volume and temperature of 0.72 atm, 9.93 L and 17 °C, respectively. How many moles of gas are present? Give answer to nearest hundredth (TWO DECIMALS) Part B: A gas system has volume, moles and temperature of 6.78 L, 0.07 moles and 713 K, respectively. What is the pressure in atm Give answer to nearest hundredth (two decimal places)
Ideal Gas Law Formula
pv=nRT
P: pressure, atm
v: volume, L
n: moles, mol
R: Gas Constant 0.0821 atm*L/mol*k (this has a unit
using all the other units)
T: temperature, K (must be in Kelvin. Add 273 if
temperature is given in Celsius)***
Kelvin = Celsius +273
300 K= 27 °C + 273 (300 degrees kelvin is equal
to 27 degrees Celsius)
