light has zero mass. Photons have zero mass.
So according to e=mc2 light must also have zero energy.
Astonishing how all these photons reach us from all the way across the universe!
But all physical things have mass

How do you find the mass of an animal?
Basically by weighing it. Although mass is not the same as weight, if you know the weight and the gravity, you can calculate the mass.Basically by weighing it.

Who discovered that light has mass?
Light does not have mass. It is a form of energy.
Is light a translucent material?
Light is not a material. Material things have mass and light has no mass.
How do you use mass in a scientific sentence?
They were trying to calculate the mass of the object.
What type of mass is light?
Light 'particles' (photons) have no rest mass.
Is light massless?
Photons have no invariant mass (the hypothetical mass they would have if they weren't moving, which cannot happen). So in that sense, light is massless. However, light (and individual photons) have energy, and we know from Einstein's famous formula that energy is related to mass. (A different formula E=hv relates energy to frequency, so we can even calculate the precise equivalent mass for any given wavelength of light). In this sense, light has mass, and this can be shown by gravitational lensing, where a large enough concentration of mass can actually bend the path of light ... precisely as would be expected if light had mass.
How do you calculate a mass of am atom?
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
Is the volume of the unknown mass needed to calculate the mass of calcium oxide?
No. you will know the volume of the unknown mass after you calculate the mass of ca0
How do you measure the mass of the black hole at the galactic center?
If you observe an object in an elliptical orbit around something, AND you know the mass of the orbiting object AND the size of the orbit, you can calculate the mass of the object at the center (more precisely, at one of the foci) of the orbit. We observe several stars orbiting the super-massive black hole at our galactic center. We can calculate their mass based on the light they give off, and we can measure their orbits over time. From this, we can calculate the mass of that black hole.
How do you calculate the atomic mass of carbon?
The same way you calculate the atomic mass of other elements.
Calculate the Mass of Sn in the tin oxide product?
Calculate the mass of Oxygen in the tin oxide
How do you calculate the atomic mass of bromine?
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
How do you calculate the mass of the atom?
Protons and neutrons= mass
How to calculate mass with volume and molarity?
Not enough information. To calculate mass, you would need volume and density (mass = volume x density).

Calculate Mass of cell?
To calculate the mass of the cell you will need to know the mass and atomic number of the element. Multiply the number of atoms by the amount of grams per mole to get the mass.
How do you calculate the mass number?
mass number= protons+nutrons
