Answer:
0.0073 g
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.010 M
Volume = 25 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 25×10⁻³ L
Thus, moles of HCl :
Moles of HCl = 0.00025 moles
Considering the reaction shown below as:-
2 moles of HCl reacts with 1 mole of 
So,
1 moles of HCl reacts with 1/2 mole of
Also,
0.00025 moles of HCl reacts with 
mole of
Mole of = 0.000125 moles
Molar mass of = 58.3197 g/mol
Mass = Moles*Molar mass = 
= 0.0073 g
Answer:
15 mL of the solute
Explanation:
From the question given above, the following data were obtained:
Solution = 50 mL
Solvent = 35 mL
Solute =?
Solution is simply defined as:
Solution = solute + solvent
With the above formula, we can easily obtain the solute in the solution as follow:
Solution = 50 mL
Solvent = 35 mL
Solute =?
Solution = solute + solvent.
50 = solute + 35
Collect like terms
50 – 35 = solute
15 = solute
Solute = 15 mL
Therefore, 15 mL of the solute is required.
Answer: For this homework question, you’ll need to look up the molar mass of AgNO₃. Use this to calculate the number of moles in the sample.
Then note that silver is (quite usually) univalent, so there will be as many moles of AgCl as there were of AgNO₃.
Ask your instructor or tutor for more in-depth training, if need be. Good luck!
