The only items are 3.730 grams of a strong including only uranium, oxygen as well as fluorine and also 0.970 gram of gas. The gas is 95.0% flourine, and the rest is hydrogen. From data establish the empirical formula of the gas.

determine the molecular formula for the solid item the create a balanced chemical formula for the response. Water is contributed to 4.267 grams of UF6.

From the information, figure out the empirical formula of the gas. What fraction of the fluorine from the original compound remains in the strong and what portion is in the gas after the response? What is the formula for the strong item?

Water is added to 4.267 grams of eqUF_6/ eq. The only products are 3.730 grams of a strong having only uranium, oxygen, and also fluorine plus 0.970 gram of gas. The gas is 95.0% fluorine, as well as the rest is hydrogen.

The elements contained in acetylsalicylic acid are hydrogen, carbon, and oxygen. The combustion of 3.000 g of the pure substance returns 1.200 g of water and 3.36 L of dry carbon dioxide, gauged at STP. Figure out the mass, in g, of each aspect in the 3.000 g sample of the compound. the only items are 3.730 g of a solid having only uranium, oxygen as well as fluorine and also 0.970 grams of gas. the gas is 95.0% by mass fluorine and also the remainder is hydrogen. 1993 An Elemental analysis of an unknown pure substance indicated that the percent make-up by mass is as follows. Utilizing the information gathered from the freezing-point clinical depression technique, compute the molar mass of the unknown substance.

Compute the mole fraction of benzene in the solution explained above. The vapor pressure of pure benzene at 35C is 150. Calculate the vapor pressure of benzene over the option defined above at 35C.

The only products are 3.730 grams of a solid containing only uranium, oxygen and fluorine as well as 0.970 gram of a gas. Identify the empirical formula of the gas. The CaC2O4 was dissolved in sulfuric acid as well as the resulting H2C2O4 was titrated with a standard KMnO4 remedy. Compose the balanced formula for the titration reaction, shown unbalanced listed below.

MnO4- + H2C2O4 + H+ Mn2+ + CARBON DIOXIDE + H2O Indicate which material is the oxidizing agent and which compound is the lowering representative. The titration of the H2C2O4 gotten required 35.62 milliliters of 0.1092 molar MnO4- service. Calculate the number of moles of H2C2O4 that responded with the MnO4 Determine the number of moles of CaCO3 in the initial example. Compute the percentage by weight of CaCO3 in the original example. 2001 B Response the complying with inquiries concerning acetylsalicylic acid, the energetic component in aspirin. The amount of acetylsalicylic acid in a solitary pain killers tablet computer is 325 mg, yet the tablet computer has a mass of 2.00 g. Calculate the mass percent of acetylsalicylic acid in the tablet computer.
