I need a correction for the wrong ones please
molar mass of the compound using ideal gas law. an tronat M. ARI dhi RT RT molecular formula of the compound. ud M dri p 32. A gas mixture consists of N2, O2, and Ne, where the mole fraction of N2 is 0.45 and the mole fraction of Ne is 0.25. If the mixture is at STP in a 5.0 L container, how many molecules of O2 are present? PK - Pa Va T To Iron (IV) sulfide reacts with oxygen gas to produce iron (III) oxide and sulfur dioxide. 4 FeS2+ 11 02 → 2 Fe2O3 + 8 SO2 How many formula units of iron (IV) sulfide must react with oxygen gas to produce 3.50 L of sulfur dioxide at 1.10 atm and 20.0 °C?
