suppose there are n molecules of Cl2.
therefore the number of moles of cl2 are
moles=n/(6.023x10^23)
therefore now the mass is equal to
mass=moles*71
thats your answer do the math
directly mass=n*71/(6.023x10^23
therefore the number of moles of cl2 are
moles=n/(6.023x10^23)
therefore now the mass is equal to
mass=moles*71
thats your answer do the math
directly mass=n*71/(6.023x10^23
