Answer:
Molecular formula = C₁₀H₂₀
Explanation:
Given data:
Empirical formula = CH₂
Molar mass = 140.27 g/mol
Molecular formula = ?
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Now we will calculate the empirical formula mass.
CH₂ = 12 × 1 + 1× 2
CH₂ = 12 +2
CH₂ = 14
n = 140.27 / 14
n = 1
0
Molecular formula = n (empirical formula)
Molecular formula = 10 (CH₂)
Molecular formula = C₁₀H₂₀
<span>The Avogadro constant, named after the scientist Amedeo Avogadro, is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. The answer, in this case, would be 0.0004999...*10^23 = (10^19)*(4.999... [any finite number of 9s]).</span>

2. Tell a Teacher .
3. And that's it .
Answer:
<h3>The answer is 82.86 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of wood = 44 g
density = 0.531 g/cm³
It's volume is
We have the final answer as
<h3>82.86 cm³</h3>
Hope this helps you
