Just as matter is defined by having mass, there cannot be matter with zero mass.
Current theories all define the "photon" (energy quantum) as having zero rest mass, although it can be treated as both a "particle" and a wave.

Can you have kinetic energy without momentum?
We don't think you can. Here's our reasoning: -- Kinetic energy of an object is [(1/2)(mass)(speed)2]. If kinetic energy is not zero, then mass can't be zero, and speed can't be zero either. -- Momentum of the object is [(mass)(speed)]. If mass isn't zero and speed isn't zero, then momentum isn't zero.
What is the mass of moving photon?
the mass of a photon is zero
What is the significance of a zero mass reading for some substances?
Explain the significance of a zero-mass reading in some substances and negative-mass readings for other substances?
Is the mass of body the same thing as the weight?
No. The weight is the mass times the acceleration. W=ma. The weight can be zero if the acceleration is zero, even if the mass is positive. Mass and weight are not the same thing.
How do you calculate the mass of light?
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
When is the mass of an electron regarded as zero?
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
Can a body have zero mass and zero weight?
no
Can mass of an object be zero?
No, but it can get fairly close to zero.
What is the mass percentage of 02?
It is zero. The number 02 is a number. It is a concept and no physical existence and no mass. So the mass percentage is zero.

What is the mass of moving photon?
the mass of a photon is zero
What value should theoretically be obtained for the intercept on a graph of mass vs volume HINT The intercept corresponds to zero mass and zero volume?
zero
What is the average weight of a shed?
The shed is of zero mass and zero weight
Which is more common a mass of zero or a weight of zero?
Depend on what exactly do you mean by 'common'. On one hand there are countless photon everywhere which has zero mass. But if you mean everyday objects, then zero weight of cause (free fall, space etc), as I don't think zero mass is even attainable at this scale.
What is the significance of a zero mass reading for some substances?
Explain the significance of a zero-mass reading in some substances and negative-mass readings for other substances?
Is the mass of body the same thing as the weight?
No. The weight is the mass times the acceleration. W=ma. The weight can be zero if the acceleration is zero, even if the mass is positive. Mass and weight are not the same thing.
What is the mass of a massless particles?
Zero.
