Answer:
20 mole of oxygen
Explanation:
1 mole of proprane reacts with 5 moles of oxygen so 4 time 5 equals 20
Answer:
Explanation:
Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules
Answer is: volume will be 3.97 liters.
Boyle's Law: the pressure volume law - volume of a given amount of gas held varies inversely with the applied pressure when the temperature and mass are constant.
p₁V₁ = p₂V₂.
p₁ = 755 torr.
V₁ = 5.00 l.
p₂ = 1.25 atm · 760 torr/atm.
p₂ = 950 torr.
755 torr · 5 l = 950 torr · V₂.
V₂ = 755 torr · 5 l / 950 torr.
V₂ = 3.97 l.
When pressure goes up, volume goes down.
When volume goes up, pressure goes down.
We know 1 mole of any atom or molecules contains
atom or molecules.
1 mole of HBr i.e 81 gm/mol contains
atom or molecules.
So, mass of
molecules is :

Therefore, mass of
molecules is 1.21 gm .
Hence, this is the required solution.
