Answer:
Structure of 2-methylpropane.
Explanation:
The given compound is 2-methyl propane.
Propane has three carbons in their parent chain and all are bonded by a single bond.
And the second carbon has methyl group.
The structure of 2- methyl propane is as follows.
Answer:
it would be 53
Explanation:
because 4.00 L at 158kPa and 28c would be 53 grams of oxygine
Mass percent is the estimation of the mass of the element in a compound in percentage form. The mass % of manganese (Mn) in potassium permanganate is 34.76 %.
<h3>What is the mass percentage?</h3>
The mass percentage is defined by dividing the mass of the element by the molecular mass of the compound followed by multiplying it by 100%. It is given as,
Mass % = (Atomic Mass of element ÷ Molecular Mass) × 100
As it is known that,
Atomic Mass of manganese = 54.94 g/mol
Molecular Mass of potassium permanganate = 158.034 g/mol
Substituting values to calculate mass % as:
% Mn = (Atomic Mass of Mn ÷ Molecular Mass of KMnO₄) × 100
= (54.94 g/mol ÷ 158.034 g/mol) × 100
= 34.76 %
Therefore, 34.76% Mn is present in KMnO₄.
