Question

a 100 gram sample of iron ore was found to contain 44g of iron. How many grams of iron are in a 450 gram sample of the ore?

Answer 1

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.
