The element iron (Fe) is 45.8% by mass of a mixture. Write both conversion ratios for the following mass percent values.
To write conversion ratios for mass percent values, we need to understand what mass percent represents. Mass percent is the ratio of the mass of a particular component to the total mass of the mixture, expressed as a percentage.
Let's assume that the total mass of the mixture is 100 grams.
The mass percent of iron (Fe) in the mixture is given as 45.8%. This means that the mass of iron in the mixture is 45.8 grams.
To write the conversion ratios:
1. The ratio of iron (Fe) mass to total mixture mass:
Fe mass / Total mass = 45.8 grams / 100 grams = 0.458
2. The ratio of non-iron mass to total mixture mass:
Non-Fe mass / Total mass = (100 grams - 45.8 grams) / 100 grams = 0.542
Therefore, the conversion ratios for the given mass percent values are:
1. The iron (Fe) mass ratio = 0.458
2. The non-iron mass ratio = 0.542
