Find energy is the wavelength is 5.2x10^-7m (Show work)
RoseWind [281]

Answer:

E = 3.825×10⁻¹⁹ J

Explanation:

Wavelength of photon = 5.2 ×10⁻⁷m

Energy of photon = ?

Solution:

Formula:

E = hc/λ

h = plancks constant = 6.63×10⁻³⁴ Js

c = speed of wave = 3×10⁸ m/s

by putting values,

E = 6.63×10⁻³⁴ Js ×3×10⁸ m/s / 5.2 ×10⁻⁷m

E = 19.89×10⁻²⁶ J.m / 5.2 ×10⁻⁷m

E = 3.825×10⁻¹⁹ J

Please help i dont understand it
Setler [38]

Answer:-  solution boiling point = 102.23 degree C (102 degree C with three sig figs).

Solution:- When a non volatile solute is added to a solvent then boiling point increases. Elevation in boiling point is directly proportional to the molality of the solution.

The equation is:

\Delta T_b=i*k_b*m

where, \Delta T_b is the elevation in boiling point, i is the Van't hoff factor, k_b is the molal elevation constant and m is the molality.

Value of i is 1 as ethylene glycol is a covalent molecule that does not break to give ions. k_b for water is \frac{0.512^0C}{m} .

We can calculate the molality from the given grams of ethylene glycol and liters of water as molality is moles of solute per kg of solvent.

Molar mass of ethylene glycol is 62 gram per mol and density of water is 1.00 kg per liter.

2.50L(\frac{1kg}{1L})

= 2.50 kg

Let's calculate the moles of ethylene glycol.

675g(\frac{1mol}{62g})

= 10.9 mol

molality of the solution = \frac{10.9mol}{2.50kg}

= 4.36m

Let's plug in the values in the equation we have on the top for elevation in boiling point.

\Delta T_b=4.36m(\frac{0.512^0C}{m})

= 2.23^0C

Boiling point of pure water is 100 degree C. So, the boiling point of the solution = 100 + 2.23 = 102.23 degree C

(If we fix the three sig figs then it could be written as 102 degree C.)
