A mole is a unit that describes an amount of a substance that has 1 unit of Avogadro's number in it. Avogadro's number is 6.022 E23.
The mass is sometimes informally called the "amount of substance", though this is not very precise. The SI unit for mass is the kilogram.
The mole is an SI unit. It is the SI unit for the amount of matter in a substance.In fact, it is an SI base unit, meaning it is defined by measurements in a laboratory and not in terms of other units.One mole of a substance is the number of entities or elementary particles in that substance equal to the number of atoms in exactly 12 g of the carbon-12 isotope.
There is no SI Base Unit for energy. The unit for energy, the joule is a Derived Unit.
No. The base unit for length is the metre. In fact, a centimeter is a no-preferred unit in the SI system, which recognises multiples of 103.
The SI unit for temperature is the Kelvin.
The base unit for the amount of a substance is an hour.

Correct, the base unit in the International System of Units (SI) for amount of substance is the mole. The mole is used to measure the amount of a substance and is defined as the number of carbon atoms in 12 grams of pure carbon-12.
The base unit of voltage is the volt, a combined unit meaning joules per coulomb.AnswerThe SI unit for voltage is the volt (symbol: V), which is a derived unit -not a base unit. There are seven base units in the SI system: metre, kilogram, second, ampere, candela, kelvin, and mole. SI units which are not base units are termed 'derived units'.
