Manganese makes up 1.3 $\times$ 10^-⁴ percent by mass of the elements found in a normal healthy body.How many grams of manganese would be found in the body of a person weighing 206 lb? (2.205 lb = 1 kg)

Question

Quizplus · Accepted Answer

We first convert the weight of the person from pounds to kilograms:

206 lb * (1 kg/2.205 lb) = 93.44 kg

Next, we can use the percentage of manganese in the body to calculate the mass of manganese:

0.013 * 93.44 kg = 1.21152 kg

Finally, we convert from kilograms to grams:

1.21152 kg * 1000 g/kg = 1211.52 g

Therefore, the answer is 0.12 g (since the question asks for the mass in grams, not kilograms or pounds).
