Chapter 5, Problem 5.139(choose chapter or problem)
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 5 2.00 atm and T 5 258C. When this mixture of gases is put in an effusion chamber, the ratio of Z molecules to Ar molecules in the effused mixture is 0.4837. Using these data, calculate the following. a. the empirical formula for Z b. the molar mass for Z c. the molecular formula for Z d. the mole ratio of Z to argon in a sample of gas obtained by five effusion steps (starting with the original mixture)
