Answer:
There are 198 grams of iron in a 450-gram sample of the ore.
Explanation:
From the given information:
Given that:
100-gram sample of iron ore is found in 44g of iron.
Thus. the grams of iron that can be found in a 450-gram sample of the iron ore can be computed as follows:
100g of iron ore = 44g of iron
450 gram of iron ore = x g of iron
x(g) of iron = ( 44g of iron × 450 gram of iron ore) / 100g of iron ore
x(g) of iron = 198 grams of iron
Thus, there are 198 grams of iron in a 450-gram sample of the ore.
