Answer:
The mass of the precipitate that AgCl is 3.5803 g.
Explanation:
a) To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute (NaCl) = 1.46 g
Molar mass of sulfuric acid = 58.5 g/mol
Volume of solution =
Putting values in above equation, we get:
0.09982 M is the concentration of the sodium chloride solution.
b)
Moles of NaCl =
according to reaction 1 mol of NaCl gives 1 mol of AgCl.
Then 0.02495 moles of NaCl will give:
of AgCl
Mass of 0.02495 moles of AgCl:
The mass of the precipitate that AgCl is 3.5803 g.
Answer : The volume of the cube is,
Solution : Given,
Density of nickel =
Number of nickel atoms =
Molar mass of nickel = 58.7 g/mole
First we have to calculate the moles of nickel.
As, atoms form 1 mole of nickel
So, atoms form
moles of nickel
The moles of nickel = 3.321 moles
Now we have to calculate the mass of nickel.
The mass of nickel = 194.94 g
Now we have to calculate the volume of nickel.
Therefore, the volume of the cube is,
