Calculations involving masses GapFill

No atoms are created or destroyed in a reaction. This is called  atom economyAvogadro's ruleconservation of massparticle theoryrelative atomic massentropy. Chemical reactions are represented using symbols to represent  volumeselectronsmoleselementsconcentrationsmasses, with numbers in front of them to  sequenceprioritisetime-stampbalanceexpandcombine the equation.

The relative formula mass of a chemical can be calculated by adding together the  ratiovolumesconcentrationsrelative atomic massesatomic numberscharges of the atoms. In a balanced equation, the relative formula masses of the products equals that of the  theoretical massreactantsmetalsmass lostprotonsair or solution. If a reaction ever seems to lose or gain mass it is because  an unreactivean unstablea radioactivean isotopica sidea gaseous product or reactant is involved, whose mass does not get measured.  ProbabilityDoubtCorrectnessReliabilityUncertaintyEstimation is a way of describing the accuracy of a measurement.

The  densityconcentrationpressureentropymassenergy level of a solution can be found by dividing the mass of solute by the volume of the solution.
