There is no law of concervation of mass anymore, it is the law of conservations of energy (since mass can be converted into pure energy, thank you Albert).

What is a closed container in relation to the law of conservation of mass?
This refers to the law of conservation of mass. It is generally used when balancing chemical reactions as it states that the total mass of the substances undergoing a chemical reaction is always the same: before, during, and after the chemical reaction. The "closed system" part means that no matter is gained from the surrounding environment nor lost to it. Keep in mind though that this law isn't valid for nuclear reactions, in which the total mass of the system does vary. In any case, you can always use the law of conservation of energy, as matter itself is a form of energy (see the famous equation E=mc2).
What does Conservation mass mean?
The law of conservation of mass/matter, also known as principle of mass/matter conservation is that the mass of a closed system (in the sense of a completely isolated system) will remain constant over time. The mass of an isolated system cannot be changed as a result of processes acting inside the system. A similar statement is that mass cannot be created/destroyed, although it may be rearranged in space, and changed into different types of particles. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products. This is also the main idea of the first law of thermodynamics. As opposed to mass conservation, the principle of matter conservation (in the sense of conservation of particles which are agreed to be "matter") may be considered as an approximate physical law, that is true only in the classical sense, without consideration of special relativity and quantum mechanics. Another difficulty with the idea of conservation of "matter," is that "matter" is not a well-defined word scientifically, and when particles which are considered to be "matter" (such as electrons and positrons) are annihilated to make photons (which are often not considered matter) then conservation of matter does not take place, even in isolated systems. Mass is also not generally conserved in "open" systems (even if only open to heat and work), when various forms of energy are allowed into, or out of, the system (see for example, binding energy). However, the law of mass conservation for closed (isolated) systems, as viewed over time from any single inertial frame, continues to be true in modern physics. The reason for this is that relativistic equations show that even "massless" particles such as photons still add mass and energy to closed systems, allowing mass (though not matter) to be conserved in all processes where energy does not escape the system. In relativity, different observers may disagree as to the particular value of the mass of a given system, but each observer will agree that this value does not change over time, so long as the system is closed. The historical concept of both matter and mass conservation is widely used in many fields such as chemistry, mechanics, and fluid dynamics. In modern physics, only mass conservation for closed systems continues to be true exactly.
What states that when one form of energy is transformed to another no energy is destroyed?
That's the law of "Conservation of Energy". It says you always end up with theexact same amount of energy you started out with.That law has been updated a bit in recent years. There used to be two separateconservation laws ... one for energy and another one for mass, and they both saidthat it couldn't be created or destroyed. Scientists were very worried when they didsome very important experiments, and they saw mass being destroyed and energybeing created! Digging in further, they discovered that energy could change into mass,and mass could change into energy. That discovery actually made things simpler, becausenow, instead of two conservation laws, we only need one. It says that mass and energycan change from one to the other, but whatever the total (mass + energy) is at thebeginning, the total (mass + energy) must be the same at the end.But how can you add them up ? How much energy makes how much mass ??And how much mass makes how much energy ???We're so happy you asked that.Maybe you've heard that [ E = M c2 ] .That's the answer to that one.
What is lavoisier's law of conservation of metter?
Antoine Lavoisier's Law of Conservation of Matter states that the total mass of the products of a chemical reaction is always the same as the total mass of the starting materials used up in the reaction.

Who proposed law of conservation of mass?
The law of conservation of mass / matter, also known as the law of mass / matter conservation (or the Lomonosov-Lavoisier law), states that the mass of aclosed system of substances will remain constant, regardless of the processes acting inside the system.An equivalent statement is that mattercannot be created nor destroyed, although it may change form. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products.The law of mass / matter conservation may be considered as an approximate physical law that holds only in the classical sense before the advent of special relativity and quantum mechanics. This historical concept is widely used in many fields such as chemistry, mechanics, and fluid dynamics. However, mass is not conserved in nuclear reactions. The law of conservation of mass was first clearly formulated by Antoine Lavoisier in1789. However, Mikhail Lomonosov(1748) had previously expressed similar ideas and proved them in experiments.

Law of conservation is what?
There are two laws of conservation. One is the law of conservation of mass, which says mass can neither be created or destroyed, only changed in form. The other is the law of conservation of energy, which says energy can neither be created or destroyed, only changed in form. These laws, formulated in the 18th & 19th century, are still used to solve physics and engineering problems today, however they are now known not to be entirely true. Einstein's theory of relativity shows that mass can be converted into energy. Nuclear bombs do this. E = mc2 means in a nuclear reaction the amount of energy created (E) is equal to the mass (m) times the speed of light (c) squared.

What instrument will you se to find the mass of objects?
Weighing balance is used to measure mass. Digital balance is also used. They give fine approximation about masses.
