Answer 2

Calculation of Impurity Content in Iron Ore

To calculate the amount of impurities in 100 kg of iron ore, we need to consider that the mass of iron in the ore is 44 kg more than the mass of impurities.

Let's assume the mass of impurities in the iron ore is x kg. Therefore, the mass of iron in the ore would be (x + 44) kg.

According to the given information, the mass of iron in the ore is 44 kg more than the mass of impurities. So, we can set up the equation:

Mass of iron = Mass of impurities + 44

Substituting the values, we have:

x + 44 = x

Simplifying the equation, we find that x is equal to 44 kg.

Therefore, in 100 kg of iron ore, there are 44 kg of impurities.

Answer:

In 100 kg of iron ore, there are 44 kg of impurities.
