because you don't the formula of the actual ore so you only know
that the mass of wolf is 10% of the ore...
you know that the proportion of tungsten is
out of 359g
(Mr of wolf) - 184g belongs to tungsten.
NOT out of
total mass of ore - 184g belongs to tungsten
so 184/359 x (mass of wolf)
= 184/359 x (10% x mass of ore)
mass of ore = 10 tonnes
