laboratory uses
In the inorganic and organometallic chemistry laboratory, silver tetrafluoroborate (AgBF4), sometimes called “silver BF-4”, is a useful reagent . In dichloromethane, silver tetrafluoroborate (AgBF4) is a moderately strong oxidant. [2] Similar to silver hexafluorophosphate , it is commonly used to replace halide ions or weakly coordinating tetrafluoroborate anions with ligands . The abstraction of the halide is driven by the precipitation of the appropriate silver pudding .
What will be the mass of 2 silver atoms?
The molar mass of silver is 108 g/mol. The formula used to calculate the mass of 2 atoms of Ag is shown below. Here, NA is the Avogadro number which is equal to 6.023×1023 6.023×10. Thus, the mass of 2 Ag atoms is 3.586×10−22g 3.586 × 10 – 22 g. The molar mass of silver is 108 g/mol. IsFor ideal gases, the specific volume is the gas constant (0.08206 L (atm) / mol (K)), represented by R, multiplied by temperature (T), and pressure (M) times pressure (M). P) Multiply divided by . Common units for specific volumes are (m3/kg), but gram per cubic centimeter (cm3/g) is also used.
