sara12345

Best ResponseYou've already chosen the best response.0forget about the formula. therez no formula. mole is not a theory. its just a number, so we use the number in conversions.

Best ResponseYou've already chosen the best response.1atomic mass means the atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units

mayankdevnani

Best ResponseYou've already chosen the best response.1u need to know whats a mole rite....well...in a part of chemistry called physical chemistry...u need to calculate mass volume etc of chemical substances....for that....to measure the number of molecules atoms etc of the compound in a given sample...we use the term moles....it gives us the number of atoms or molecules..in the given amount of specimen....it accualy is 6.023* \[10^{23}\] units....just as a dozen means 12 units...so one mole of money means...6.023*10^23 rupess...

sara12345

Best ResponseYou've already chosen the best response.0so u can use the ratio \(\frac{1 mol}{atomic\ mass}\) in your conversions

sirm3d

Best ResponseYou've already chosen the best response.0a mole describes a fixed number of similar atoms or molecules a dozen means 12, a mole of nitrogen gas means 6.022x10^23 molecules of nitrogen gas

Best ResponseYou've already chosen the best response.1yaa i know but what's the formula of mole

amriju
 2 years ago
Best ResponseYou've already chosen the best response.1now the mole is very special....since all that atomic weight u see is the weight of one mole of an atom in grams....same for moleclar wt.....also....for any gas..one mole of the gas occupies a volume of 22.4 litres at STP....so now u know that moles=Mass of the given specimen/ mol or atomic masss ( accordingly if its a molecule or an atom that the specimen is made of)

sirm3d

Best ResponseYou've already chosen the best response.0the number of moles of Na+ is the same as the number of moles of NaCl, which is 2000/58.5 moles

UnkleRhaukus

Best ResponseYou've already chosen the best response.0the NaCl molecule has one sodium atom and one chlorine atom only

UnkleRhaukus
 2 years ago
Best ResponseYou've already chosen the best response.0one mole of NaCl has 6x10^23 molecules, so in one mole of NaCl there will be 6x10^23 sodiums and 6x10^23 chlorines

mayankdevnani

Best ResponseYou've already chosen the best response.1no so whats the answer

UnkleRhaukus
 2 years ago
Best ResponseYou've already chosen the best response.0the H_2O molecule has two hydrogen atoms and one oxygen atom one mole of H_2O has 6x10^23 molecules, so in one mole of H_2O there will be 12x10^23 Hydrogens and 6x10^23 Oxygens

sara12345

Best ResponseYou've already chosen the best response.0this is the logical order we study things in chemistry : 1) atoms models 2) compounds 3) reactions

sara12345

Best ResponseYou've already chosen the best response.0mol concept is very basic, we learn it along with atomic mass and molar mass, in first module, atomsmodels

sara12345

Best ResponseYou've already chosen the best response.0once we get confident with atoms, mole conversions to grams and number of atoms, fully, we move to next module compounds.
