Explanation:
Moles:
RFM of potassium sulphate :
substitute:
In volume of 5.00 l:
Answer: mass m = M·c·V
Explanation: M(CaCl2) = 110.98 g/mol, c= 0.15 mol/l,
n=m/M= cV, volume of Solution is not mentioned
True because I had the test
Answer:
Magnesium chloride (MgCl₂) > Potassium bromide (KBr) > Butanoic acid (C₃H₇COOH) > Sugar (C₆H₁₂O₆) (Conductivity)
Explanation:
The given samples:
<u>Magnesium chloride (MgCl₂):</u>
It is a strong salt which dissociates 100% into 3 ions, 1 Mg²⁺ and 2 Cl⁻
<u>Sugar (C₆H₁₂O₆):</u>
It is a carbohydrate and will have 0% dissociation and thus, no ions.
<u>Butanoic acid (C₃H₇COOH):</u>
It is a carboxylic acid (weak acids) which partially dissociates.
<u>Potassium bromide (KBr):</u>
It is a strong salt which dissociates 100% into 2 ions, K⁺ and Br⁻.
Thus, Conductivity is directly proportional to the numbers of ions dissociated in the solution and hence will conduct more electricity.
So,
<u>Magnesium chloride (MgCl₂) > Potassium bromide (KBr) > Butanoic acid (C₃H₇COOH) > Sugar (C₆H₁₂O₆) (Conductivity)</u>
