Answer: iron atoms
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.
contains= 2 atoms of iron
contains= atoms of iron
thus 0.32 moles of contains= atoms of iron
Thus the sample would have iron atoms.
My answer will be B and D
the system is in constant temperature
so it follows Boyle's law
i.e.P1V1=P2P2
where P1=initial pressure=788 tour
P2=final pressure= ?
V1=initial volume=235 ml
V2=final volume=0.115 ml
