Answer:
7.01 mol CH4
Explanation:
STP means standard temperature and pressure, so they are basically telling you that the gas is at 1 atm and 273 K (0 degrees celsius). Now that we have the pressure, volume, and temperature we can use the ideal gas law and solve for n or moles
PV=nRT
n=PV/RT
n=(1)(157)/(0.08206)(273)
n=7.0081 (round to 3 sigfigs)
n=7.01 mol
Answer:
The rate of gas diffusion is directly proportional to temperature
Explanation:
The rate of gas diffusion is
a) directly proportional to square root of temperature
b) inversely proportional to the square root of density
c) directly proportional to pressure
d) inversely proportional time and square root of molecular mass
Thus, option A is correct
A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
