Stearic acid formula is CH₃(CH₂)₁₆COOH
The molecular mass of stearic acid is 284.48 g/mol
The mass of stearic acid in 1 ml of solution is 0.1 g
Therefore number of moles in 1 ml is - 0.1 g / 284.48 g/mol = 0.000352 mol
Molarity is number of moles in 1 L of solution
If 1 ml contains - 0.000352 mol
Then 1 L solution contains - 0.000352 /1 x 1000 = 0.352 mol/L
Therefore molarity is 0.352 M
Answer:
The answer is
<h2>55.56 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of aluminum = 150 g
density = 2.7 g/cm³
The volume is
We have the final answer as
<h3>55.56 cm³</h3>

<span>When an atom or compound is oxidized, its properties change. For example, when an iron object undergoes oxidation, it is transformed because it has lost electrons. Unoxidized iron is a strong, structurally sound metal, while oxidized iron is a brittle, reddish powder. The diagram below illustrates what happens to an atom of iron as it is oxidized
