Main distinction – AMU vs Grams

The terms amu and grams are provided to measure the mass of substances. Therefore, grams deserve to be converted into amu units and amu units have the right to be converted right into grams as well. Gram is a larger unit when compared to amu, yet gram is a smaller sized unit contrasted to other units supplied for the measure of mass. The hatchet amu represents “atomic massive unit” and is supplied for the measurements of very little substances such together atoms. The amu is the unit the is offered to to express the atom mass of a chemical element. The main difference between amu and also grams is that amu is provided to to express the massive in atomic level vice versa, gram is used as a metric unit the mass.

Key Terms: Amu, Atom, atomic Mass, Grams, Mass, Neutrons, Nucleus, Protons

What is AMU

The term amu deserve to be characterized as a unit the mass the is same to precisely one twelfth that the mass of carbon-12 atom. The ax amu means “atomic massive units”. The value of one twelfth of the massive of carbon-12 atom is 1.660538921 x 10−27 kg. Therefore, 1amu is equal to 1.660538921 x 10−27 kg the mass. This is about equal come the fixed of a proton or a neutron. (One carbon atom the caron-12 isotope is created of 12 protons. Then the mass of one twelfth of the atom is same to the fixed of a proton).

When the massive of one atom is offered in the units of amu, it gives the amount of the masses of every protons and also neutrons that are in the cell core of the atom. Electrons have actually a negligible fixed when compared to protons and also neutrons. However, since the number of protons is a unique characteristic for any given chemistry element, the massive of that variety of protons should likewise be distinctive for every element. The total mass the the proton is called as the atomic number of an element. Therefore, both atomic number and also atomic fixed are offered in the regards to amu.

The principle amu to be introduced because the masses the atoms are minute and cannot it is in measured by the devices that we use to measure hefty substances. For example, the massive of a proton in grams or kilograms is a very tiny amount the is not that straightforward to it is in handled. However when that is offered in amu, it is really easy to handle.

What room Grams

Gram is a unit provided to measure up a fixed of a substance. It have the right to be characterized as the mass the is same to one thousandth of a kilogram (1/1000 kg). The symbol for this unit is “g”. The older meaning for gram is “the fixed of one cubic centimeter the water in ~ 4oC. The gram is offered in measuring solid substances in the day to day life.

When using the symbol v a value, one need to use a an are between the value and the symbol. Because that example, if over there is a compound having actually a fixed of 450 of grams, then it is provided as “450 g”. The gram was a fundamental unit because that measuring the mass according to the “centimeter-gram-second device of units”. Yet later the was changed with kilogram (kg) in the SI unit system.

Relationship in between AMU and Grams

The terms amu and also grams deserve to be interconverted. This means amu have the right to be converted right into grams and also grams have the right to be converted into amu together well.

For example, the atomic load of carbon-12 isotope is 12 g/mol. That means one mole that carbon-12 isotope weighs 12 g. The atomic mass that carbon-12 isotope is 12 amu. Therefore,

1 mol that carbon-12 = 12 g 12 amu = 12 g / 1 mol = 12 g / 6.023 x 1023 Then, 1 amu = 1.66 x 10-24 g

Difference in between AMU and Grams

Definition

AMU: Amu deserve to be defined as a unit that mass that is equal to exactly one twelfth the the mass of carbon-12 atom.

Gram: Gram deserve to be identified as the mass that is same to one thousandth a kilogram (1/1000 kg).

Symbol

AMU: The symbol supplied to express “atomic mass unit” is amu.

Gram: The symbol because that grams is “g”.

Applications

AMU: The unit amu is provided for measurements in atomic level.

Gram: Gram is used in measuring huge substances when compared to amu.

Conclusion

The state amu and grams are used in measuring masses that substances. Gram is provided in ours day to day life come express the fixed of products that we use whereas amu is supplied for minute scale measurements. The main difference in between amu and grams is that amu is offered to refer the mass in atom level vice versa, gram is offered as a metric unit of mass.
