## How do you convert joules to nanometers?

To calculate Joules from nanometers, multiply the speed of light by the plank constant and then divide by the wavelength in meters..

### How do you calculate wavelength from kJ mol?

Solution:

1. Convert kJ to J: 3.82 x 10-22 kJ times (1000 J / 1 kJ) = 3.82 x 10-19 J.
2. What you now do is combine these two equations: E = hν and λν = c.
3. Calculate the wavelength in meters: (3.82 x 10-19 J) (λ) = (6.626 x 10-34 J s) (3.00 x 108 m/s)

How do you convert kJ mol to J photon?

Re: How to convert kJ/mol to J Answer: Cancel out the 1/mol unit by dividing by the Avogadro constant. Then convert kJ to J by multiplying the kJ value by 1000 (because of the conversion factor 1 kJ = 1000 J).

How do you convert nanometers to kilojoules?

The kilojoules unit number 0.0010 kJ converts to 1 N-m, one Newton meter.

## How do you calculate energy from nanometers?

The equation for determining the energy of a photon of electromagnetic radiation is E=hν , where E is energy in Joules, h is Planck’s constant, 6.626×10−34J⋅s , and ν (pronounced “noo”) is the frequency. You have been given the wavelength λ (pronounced lambda) in nanometers, but not the frequency.

### How do you convert joules to kJ mol?

Accepted book enthalpies are in the units kJ/mol. Simply convert J to kJ by dividing by 1000. Since 1 kJ=1000 J. You would use the moles of the product.

How do you calculate kJ mol?

Calculating energy changes

1. = 100 × 4.2 × 20 = 8,400 J.
2. It is also useful to remember that 1 kilojoule, 1 kJ, equals 1,000 J.
3. Moles of propane burned = 0.5 ÷ 44 = 0.01136.
4. So, the molar enthalpy change, ∆H = 8.4 ÷ 0.01136 = 739 kJ/mol.

How do you convert nanometers to joules?

The joules unit number 1.00 J converts to 1 N-m, one Newton meter.

## How do you convert kJ mol to kJ G?

As you know, this conversion factor is the molar mass of the given compound. In order to convert kilojoules per gram to kilojoules per mole, you need to multiply by grams per mole. Now, let’s say that you’re dealing with a compound that has a molar mass of x g mol−1 .

### How do you convert joules to moles and joules?

Since 1 mole = 6.02214076×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214076×1023 particles, 1.66054×10−24 joule per particle.

How to convert J mol to kJ mol?

1 J/mol = 0.001 kj/mol; 1 kj/mol = 1000 J/mol

How is one kilojoule related to one newton metre?

One Kilojoule is 1,000 Newton Metre, ie the work done or energy transfered to an object when a 1,000 Newton force acts on it over one metre. It can also be defined as the heat energy dissipated by a current of 1,000 amperes passing through a one Ohm resistor for one second

## Which is the correct prefix for a kilojoule?

Prefix or symbol for kiloJoule is: kJ. Technical units conversion tool for energy measures. Exchange reading in newton meters unit N-m into kiloJoules unit kJ as in an equivalent measurement result (two different units but the same identical physical total value, which is also equal to their proportional parts when divided or multiplied).

### How to calculate the energy of one mole?

The prefix “kilo” means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence “per mole”. To get the energy for one molecule, divide kJ/mol by Avogadro’s number, 6.022 x 10 23. Kilocalories per mole (kcal/mol)
