Wealthiest 61834

Iron is produced in a blast furnace from iron ore. The wealthiest iron ore is magnetite, which contains 45-70% iron. How much magnetite do we need to get 3 tons of iron?

Correct answer:

a =  4.2857 t
b =  6.6667 t

Step-by-step explanation:

p1=70%=10070=107=0.7 m=3 t  a p1 = m  a=m/p1=3/0.7=4.2857 t
p2=45%=10045=209=0.45  b=m/p2=3/0.45=6.6667 t
