a characteristic mass of 1.1 ng for pb was found. calibration was performed using different masses of solid alizarin red-naphthalene spiked with pb reference solution. results were considered satisfactory, for concentration ranging from 30 and 50 渭g l-1, regarding to both accuracy (recoveries ...
The crystallographic data are supported by mass spectra of acetonitrile (MeCN) solutions of the filtration residue showing Si9 species (Fig. 5), confirming the presence of nine-atomic clusters in the dried filtration product. Additionally, 1H NMR (Fig. 6) of K1-x[K(2.2.2- crypt)]2+x[Si...
Find the molar mass, moles of each element, and number of atoms of each element for 0.9992 g NaCl, 0.9822 g C12H22O11, 0.9510 g NH4Cl, 0.9723 g C6H5OH, and 1.0038 g C9H20. Find the molar mass of NaCl. What is the mass of two moles of NaCl? ...
The solubility of these monovalent metal salts strongly depends on the size and the polarizability of the metal, the solvent, and the halogen substituent.91,155 While the cesium salts are sparingly soluble in water (e.g., solubility of Cs2[B12Br12] at 25 °C is 6.36 mass %), the ...
