Given the mass percentage of Manganese in a normal healthy body is
It means that g Mn is present in 100 g of the body mass.
Given that the person weighs 196 lbs
Converting the person's mass to g: The conversion factors to be used are: 1 kg = 2.205 lb; 1 kg = 1000 g
Calculating the mass of Mn in the person's body:
Therefore, 0.116 g Mn is present in a person weighing 196 lbs.
Answer:
Explanation:
How many moles?
moles=Mass/Molar Mass
Here we have the mass and we can get the molar mass from the periodic table (Na=23, C=12, O=16) So
Molar mass= 23+12+(16x3)=83
Then Moles=0.025/83=<u>1/3320</u>
