In the si system of units, the mole is one of seven base units. it is frequently used in chemical calculations. however, a mole of something is just a particular quantity of it. it is not a unit of measure in the way that meters, seconds, and kilograms are. calculations performed with the number of moles of a substance could also be performed with the number of particles of a substance. based on this information, do you think that the mole should be considered a base unit in the si system? explain why or why not.

We have to discuss here whether mole should be considered as a base unit in SI system or not.

The answer is-   mole is considered as base unit in SI system.

There are seven base units in the SI system. They are- kilogram (kg) for mass, second (s) for time, kelvin (K) for temperature, ampere (A) for electric current, mole (mol) for the amount of substance, candela (cd) for luminous intensity and meter (m) is for distance.

Mole is defined as the amount of substance that contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12. One mole contains exactly 6.022 X 10²³ elementary entities.

This number  6.022 X 10²³ is the fixed numerical value which is called Avogadro number which is universally accepted number. Hence mole is also base unit in the SI system.

Answer

This number  6.022 X 10²³ is the fixed numerical value which is called Avogadro number which is universally accepted number. Hence mole is also base unit in the SI system.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
