Three gases 8.00 g of methane, 18.0 g of ethane,C2H6, and an unknown amount of propane, C3H8 were added to the same 10.0 L container. At 23.0degrees C, the total pressure in the container is 4.20atm . Calculate the partial pressure of each gas in the container. Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first, then ethane, then propane.
Copper and zinc (elements 29 and 30, respectively) appear next to each other on the periodic table. A 5.50 g sample of zinc has a volume of 0.770 mL, while a 5.50 g sample of copper has a volume of 0.616 mL. Why?
