Answer:
0.1988 M
Explanation:
Molarity of a solution can be defined as the number of moles of solute present in that solution per volume of the solution in liter. Mathematically, molarity can be expressed as:
number of moles/volume (liter)
Also, moles = mass of substance/molar mass
mass of sucrose = 6.4475 g
molar mass of sucrose = 324.3 g/mol
moles of sucrose = 6.4475/324.3 = 0.0199
volume of solution = 100.00 ml = 0.1 liter
Hence, molarity of the solution = 0.0199/0.1
= 0.1988 M
The molarity of the solution is 0.1988 M.
We know, E = Planck's constant * speed of light / wavelength
Here, h = 6.62607004 × 10-34 m2 kg / s
c = 3 * 10^8 m/s
w = 4966.36 nm = 4966.36 * 10^-9m = 4.96636 * 10^-6 m
Substitute their values,
E = (6.62607004 × 10-34) (3 * 10^8) / (4.96636 * 10^-6)
E = 19.88 × 10^-26 / 4.96636 * 10^-6
E = 4 × 10^-20 J
E = 4 × 10^-20 / 10^3
E = 4 × 10^-23 KJ
In short, Your Answer would be: 4 × 10^-23 KJ
