Atoms are the basic units of matter and the defining structure of elements. The term "molecule" refers to the smallest particle of an element or compound that has the chemical properties of that element or compound. A salt is a compound made up of a metal and a nonmetal. In the majority of cases, the metal is a sodium (Na) or potassium (K) cation, and the nonmetal is an anion such as chloride (Cl) or sulfate (SO4). Thus, a salt is really nothing more than the product of the reaction between a base and an acid.
The number of molecules in 2.5 mol of NaCl is equal toAvogadro's number, which is 6.02 x 10^23. This means that there are 602,000,000,000,000,000,000,000 molecules of NaCl in 2.5 mol.
How many atoms are in 2.5 mol of NaCl?
The number of atoms in a molecule of a compound is equal to the number of moles of the compound multiplied by Avogadro's number. Therefore, the number of atoms in 2.5 mol of NaCl is 2.5 mol x 6.02 x 10^23 atoms/mol, or 1.51 x 10^24 atoms.
What is the molar mass of NaCl?
The molar mass of NaCl is 58.44 g/mol. This value is determined by the ratio of the masses of Na and Cl atoms in the molecule. There are 11.99 grams of Na for every 1 gram of Cl.
What is the percent composition of NaCl?
The percent composition of NaCl is 58.44%. This means that 58.44% of NaCl is made up of sodium, and the rest is chlorine.
