How many representative particles are in 6.8 g of #H_2O
The mole corresponds to a given count of particles. Usually the particles counted are chemically identical entities, individually distinct. For example, a solution may contain a certain number of dissolved molecules that are more or less independent of each other. However, in a solid the constituent particles are fixed and bound in a lattice arrangement, yet they may be separable without losing their chemical identity. Thus the solid is composed of a certain number of moles o… The number of moles of a substance in a sample is obtained by dividing the mass of the sample by the molar mass of the compound. For example, 100 g of water is about 5.551 mol of water. [8] The molar mass of a substance depends not only on its molecular formula, but also on the distribution of isotopes … Meer weergeven The mole (symbol mol) is the unit of amount of substance in the International System of Units (SI).
