They need a counting unit to count the number of atoms, molecules, or formula units of a substance.
There are a lot of reasons why chemists will use the mole. The mole is a unit of measurement that is mathematically sound when counting atoms and molecules.
A measurement unit for the quantity of a substance was needed.
The term mole was proposed by Wilhelm Ostwald, a German chemist, in 1893 - mole is derived from molecule.
Mol is a unit of concentration in the SI.
In the SI mole is the unit for the amount of substance; this is a convention.
0.25 x 6.022 x 10^23=1.05055 x10^23
a chemist works in lab and sometimes a field because remember and a chemist needs objects or particles to answer some questions . so i will have to say that a chemist in the lab and on the field
A chemist studies chemistry. However, in some places a pharmacist can be called a chemist.
nope
Scientists work in various types of laboratories. They are most often identified by their specialty, not by the fact they work in a lab.There are also labs for engineering, such as civil, ceramic, mechanical, electrical, aeronautical, each staffed with their own specialists.A chemist may work in a chemical laboratory or a dispensary.A forensic scientist might work in a crime lab and may be a chemist or biologist or other specialist, by education.
Chemists organize information about atoms.
A chemist must work with all types of materials.
Optical Tweezers can only be useful on individual atoms. What they are is steerable beams of light used to move atoms around.
a chemist may work at either in a government agency or in industrial business or in an academe/universities

They use it
a chemist studies familiar & unfamiliar chemicals, elements. Chemist try to find advanced information about chemicals &try to prove it. They give this to peoples.
The way to work this is out is to first find the mass of one mole of H2SO4 .(98.08 grams). 10 grams is therefore 10/98.08 moles- = 0.102 moles of sulfuric acidEach mole of sulfuric acid contains gram atom of sulfur so we have .102 moles sulfur..if you want the actual count of atoms multiply by avogadros number which is6.0221415 × 1023 (most teachers will accept using 6.022 instead of the longer version)
textile chemists work in ether a lab or an office.
