mass (m) = ? , volume = 18.0 ml , density = 1.42 g/ml .

I hope I helped you^_^
Answer:
0.1 M NaOH, 3 M NH3, 0.01 M CH3COOH, 0.01 M H2SO4, 0.1 M HCl
Explanation:
Strong acids are more acids than weak acids. In the same way, strong bases are more basic than weak bases that are in the same concentration.
Then, the more concentrated acid or base will be more acidic or basic.
CH3COOH. Weak acid
NaOH. Strong base
H2SO4. Strong acid
NH3. Weak base.
HCl. Strong acid
The less acid (More basic):
<h3>0.1 M NaOH, 3 M NH3, 0.01 M CH3COOH, 0.01 M H2SO4, 0.1 M HCl</h3>
Strong base, weak base, weak acid, diluted strong acid, undiluted strong acid
B will be the one I think tbh
Complete Question
49.9 ml of a 0.00292 m stock solution of a certain dye is diluted to 1.00 L. the diluted solution has an absorbance of 0.600. what is the molar absorptivity coefficient of the dye
Answer:
The value is
Explanation:
From the question we are told that
The volume of the stock solution is
The concentration of the stock solution is 
The volume of the diluted solution is 
The absorbance is 
Generally the from the titration equation we have that

=> 
=> 
Generally from Beer's law we have that

=> 
Here l is the length who value is 1 cm because the unit of molar absorptivity coefficient of the dye is 
So
=>
