Answer:
the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30
Explanation:
Given the data in the question;
The M⁺ peak comes from all ¹²₆C atoms
so, the probability in cholesterol, C₂₇H₄₈O is ( 98.9% )²⁷ = ( 0.989 )²⁷ = 0.7418
The M+1 peak comes from the isotopic carbon ¹³₆C.
so, the probability in cholesterol is ⇒ 1.10% × ( 98.9% )²⁶ = 0.011 × ( 0.989)²⁶
The probability for 27 carbons is ⇒ 27 × 0.011 × ( 0.989)²⁶ = 0.2228
Therefore, the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30
Answer:
Number of moles = 0.003 mol
Explanation:
Given data:
Molarity of HCl = 0.300 M
Volume = 10.0 mL (0.01 L)
Number of moles of HCl added = ?
Solution:
Formula:
Molarity = number of moles / volume in litter
Number of moles = Molarity × volume in litter
Number of moles = 0.300 mol/L × 0.01 L
Number of moles = 0.003 mol
Abstract:
Ionic compounds can only conduct electricity if their ions are free to move. So ionic compounds do not conduct electricity when they are solid, but they do conduct electricity when they are dissolved in water or when they are melted<span>.
Answer:
</span>Ionic compounds can conduct electricity when dissolved in water or melted because <span>the ions are free to move.
Answer choice: </span><span>C. the ions are free to move.</span>
