Given that a particular photon has a frequency of 2.2 x 10'7 Hz, calculate the photon's energy. Submit your answer in
BlackZzzverrR [31]

Answer:

E = 15×10⁻²⁹ J

Explanation:

Given data:

Frequency of photon = 2.2× 10⁷ Hz

Energy of photon = ?

Solution:

Formula:

E = h.f

h = 6.63×10⁻³⁴ Js

by putting values,

E = 6.63×10⁻³⁴ Js × 2.2× 10⁷ s⁻¹

E = 14.586 ×10⁻²⁹ J

E = 15×10⁻²⁹ J

The energy of photon is 15×10⁻²⁹ J.

You purchase a bottle of concentrated sulfuric acid from a chemical supplier. The bottle reads Sulfuric acid (95% w/w) plastic c
My name is Ann [436]

Answer:

The molarity of the sulfuric acid is 0.018 M

Explanation:

The molarity of a solution is the number of moles of the solute (sulfuric acid in this case) in a 1-liter solution.

Every 100 g of the solution, we have 95 g sulfuric acid because its concentration is 95% w/w.

With the density, we can calculate how many liters are 100 g of solution:

density = mass / volume

1.85 g / ml = 100 g / volume

volume = 100 g / 1.85 g/ml

volume = 54.1 ml or 0.0541 l

Now, we know that we have 95 g sulfuric acid in 0.0541 l solution. In 1 l, we have then:

1 l * 95g / 0.0541 l = 1.756 g sulfuric acid.

But we want to know how many moles sulfuric acid we have per liter. Then, using the molar mass, we can calculate how many moles there are in 1.756 g sulfuric acid:

1.756 g * 1 mol / 98.08 g = 0.018 mol

The molarity is 0.018 M
