100 Chemical Analysis
200 Chemical Analysis
Explain how the empirical formulas of hydrocarbons are determined.
300 Chemical Analysis5.0 g of a mixture containing some Ag was analyzed to determine the percent Ag in the mixture. The mixture was dissolved in water and excess NaCl was added. What mass of AgCl formed if the mixture was 75% silver?
400 Chemical Analysis
7.321 g of an organic compound containing carbon, hydrogen, and oxygen was analyzed by combustion. 17.873 g of carbon dioxide and 7.316 g of water was produced. Find the empirical formula.
500 Chemical Analysis
0.1101 g of a compound containing C, H, and O was combusted to produce 0.2503 g CO2 and 0.1025 g of H2O. The molar mass of the compound was 115 g/mol. Find the empirical and molecular formulas.
100 Molarity
200 Molarity
How would you make 100.0 mL of a 6 M solution of sodium chloride in the laboratory?
300 Molarity
