calculate formula unit mass of CaCl, AlCl³ ,NaOH, NaCl ,k²CO, ZnO
Answers
correct answer
1) CaCl2 :
Calcium chloride is an important calcium salt that has many household and industrial applications. Formula and structure: The chemical formula of calcium chloride is CaCl2, and its molar mass is 110.983 g/mol. It is an ionic compound consisting of the calcium cation (Ca2+) and two chlorine anions (Cl-).
2)AlCl3 :
You can view more details on each measurement unit: molecular weight of AlCl3 or grams This compound is also known as Aluminium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles AlCl3, or 133.340538 grams.
3)NaOH :
The molar mass of sodium hydroxide is 40.00⋅g⋅mol−1 ... But this, BY DEFINITION, specifies the mass of Avogadro's number formula units of sodium hydroxide.... i.e. 6.022×1023⋅formula units of sodium hydroxide per mole.
4)ZnO :
Answer: The formula unit mass of ZnO is 81u, is 62u and that of is 138u. ... Formula unit mass is defined as the sum of the atomic masses of all atoms that are present in a formula unit of the given compound. It is calculated by adding the atomic masses of all the atoms that are present in one formula unit.
