Answer:
19.18g of iron
Explanation:
To find the mass of iron, we simply find the amount of the ore in grammes that corresponds to 17.7% iron.
We can do this mathematically. We simply place the 17.7 over 100 and multiply by the total mass of the iron.
The mass of iron in the ore is thus: 17.7/100 * 92.3 = 19.18g
The ore simply contains a mass of 19.18g of iron
