Answer: 1.72cm
Explanation:
First let us calculate the mass of titanium that contain 2.86×10^23 atoms..
1mole of a substance contains 6.02x10^23 atoms as we have come to understand from Avogadro's hypothesis. Therefore, 1mole of titanium also contains 6.02x10^23 atoms.
1mole of titanium = 48g
1mole (i.e 48g) of titanium contains 6.02x10^23 atoms,
Therefore Xg of titanium will contain 2.86×10^23 atoms i.e
Xg of titanium = (48x2.86×10^23)/6.02x10^23 = 22.8g
Next, we must find the volume of titanium
Density of titanium = 4.5g/cm^3
Mass of titanium = 22.8g
Volume =?
Density = Mass /volume
Volume = Mass /Density
Volume = 22.8/4.5
Volume = 5.07cm^3
Now we can find the edge length:
Volume = 5.07cm^3
Length =?
V = L^3
L = cube root (V)
L = cube root (5.07)
L = 1.72cm
Answer: 5 Liters
Explanation:
According to the dilution law,
where,
= concentration of first solution = 24%
= volume of first solution = x L
= concentration of second solution = 14%
= volume of second solution = (10-x) L
= concentration of final solution = 19%
= volume of final solution = 10 L
Putting i the values, we get:
Therefore, 5 Liters of the 24% acid solution are used to make 10 liters of the 19% acid solution.
