A mixture of two metals is analyzed by reacting it with dioxygen to completely convert the metals to their oxides. When 3.10000 grams of a zinc/iron mixture is reacted, it produces 4.2749 grams of a mixture of Fe2so3 and zno. What is the mass percent, expressed to the proper number of significant figures, for each metal in the original metal mixture? Define all variables, show units, and show algebraic steps to your the answers.
Three gases (8.00 g of methane, CH4, 18.0 g of ethane, C2H6, and an unknown amount of propane, C3H8) were added to the same 10.0-L container. At 23.0 deg C , the total pressure in the container is 3.60 atm. Calculate the partial pressure of each g..
