Zinc (Zn) is a ROTI®Star CRM for volumetry, an elemental metal identified by CAS number 7440-66-6 and EG number 231-175-3. Its empirical formula is Zn, the molar mass is 65,37 g/mol and the density is 7,14 g/cm³. These scientific constants support mass-to-mole calculations in volumetric analysis. The material is packed as 100 g in HDPE, the stated laboratory unit for this article. As a ROTI®Star CRM for volumetry, zinc is selected where elemental metal is required in volumetric procedures. Manufacturer Carl ROTH states the molar mass of 65,37 g/mol and the density of 7,14 g/cm³ for this grade. The CAS number 7440-66-6 and EG number 231-175-3 provide the catalogue identity of the element. HDPE packaging of 100 g suits laboratory handling of the solid metal. Volumetric work can use the given molar mass when converting weighed portions into amount of substance. This ROTI®Star CRM zinc offering for volumetry therefore combines elemental identity, documented physical data and a 100 g HDPE pack.
