A structural formula for an organic compound that depicts each valence bond as a short line especially : the hexagonal ring formula for benzene
Answer:
2.275x10⁶g of CN⁻¹ were dissolved in the sample
Explanation:
Molarity is defined as the ratio between moles of solute and liters of solution.
If a CN⁻¹ solution has a concentration of 25mM, there are 0.025 moles of CN⁻¹ per liter of solution.
If the sample has a colume of 3.5x10⁶L, moles of CN⁻¹ are:
3.5x10⁶L × (0.025moles / L) = <em>8.75x10⁴ moles of CN⁻¹ in the sample of water.</em>
In grams (As molar mass of CN⁻¹ is 26g/mol):
8.75x10⁴ moles CN⁻¹ × (26g / mol) = <em>2.275x10⁶g of CN⁻¹ were dissolved in the sample</em>

The reason why perchloric acid is more acidic that ethane is because the hydrogen in perchloric acid is bonded to oxygen which is more electronegative than carbon.
The acidity of a substance depends largely on the ease with which the X-H bond is broken. If the electron density is tilted towards the atom X, then the X-H bond is weaker and the substance is more acidic.
The polarity of the X-Y bond depends on the electronegativity of X. In the case of perchloric acid and ethane, oxygen is more electronegative than carbon hence the O-H bond in perchloric acid is more easily broken than the C-H bond in ethane.
