Answer:
Mass percent of Mn is 34.76 %
Explanation:
<em>Mass percent</em> of an element is the mass of that element divided by the total mass of the elements forming that compound (or molecular mass.
So,
Mass percent of Mn will be given as,
%Mn = Atomic Mass of Mn / Molecular Mass of KMnO₄ × 100
Atomic Mass of Mn = 54.94 g/mol
Molecular Mass of KMnO4 = 158.034 g/mol
Putting values in above formula,
%Mn = 54.94 g/mol ÷ 158.034 g/mol × 100
%Mn = 34.76 %

<u>Given:</u>
Diameter of a red blood cell = 0.000008
<u>To determine:</u>
The scientific notation corresponding to the given number
<u>Explanation:</u>
Scientific notation is a concise way of representing a very large or small number. It is written in two parts:
Given Number = Digits * Power of 10
In this case we have:
0.000008 = 8.0 * 10⁻⁶
yes. I think
