A 1.000- g sample of XI2 is dissolved in water, and excess silver nitrate is added to precipitate all of the iodide as AgI. The mass of the dry AgI is found to be 1.375 g. Calculate the atomic weight (mass) of X.
Answer to relevant QuestionsA substance X2Z has the composition (by mass) of 40.0% X and 60.0% Z. What is the composition (by mass) of the compound XZ2? Element X forms both a dichloride (XCl2) and a tetra-chloride (XCl4). Treatment of 10.00 g of XCl2 with excess chlorine forms 12.55 g of XCl4. Calculate the atomic weight (mass) of X and identify X. Pure carbon was burned in an excess of oxygen. The gaseous products were CO2 72.0 mol% CO 16.0 mol% O2 12.0 mol% How many moles of O2 were present in the initial reaction mixture for every mole of carbon? A compressed-gas cylinder contains 1.00 × 103 g of argon gas. The pressure inside the cylinder is 2050. psi (pounds per square inch) at a temperature of 18oC. How much gas remains in the cylinder if the pressure is ...A compound Z is known to have a composition of 34.38% Ni, 28.13% C, and 37.48% O. In an experiment 1.00 L of gaseous Z is mixed with 1.00 L of argon, where each gas is at P = 2.00 atm and T = 25oC. When this mixture of gases ...
