The distance from one crest to another crest or from one trough to another trough is called wavelength. Hope it helps
The molecular formula C₅H₁₀O₅ and The scaling factor =5
<h3>Further explanation</h3>
Given
Molar mass = 150 g/mol
The empirical formula = CH₂O
Required
The scaling factor
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
<em>n = the scaling factor</em>
(CH₂O)ₙ=150 g/mol
(12+2+16)ₙ=150
(30)ₙ=150
n=5
The molecular formula : C₅H₁₀O₅
Answer: Option (b) is the correct answer.
Explanation:
When there are more number of hydroxide ions in a solution then there will be high concentration of or hydroxide ions. As a result, more will be the strength of base in that particular solution.
A base is strong when it readily dissociate into its ions in the solution. When a base is strong, then it does not matter at what concentration it is dissolved in the solution because despite of its low concentration it will remain a strong base.
Thus, we can conclude that out of the given options, the statement even at low concentrations, a strong base is strong best relates the strength and concentration of a base.
