1.	Calculate the mass of oxygen required at STP to convert 2.4g of graphite into carbon dioxide?
Answer» L equation for the process is:C+O2→CO2 For the above reaction, 1 MOLE of O2 will burn 1 mole of C completely.In 2.4 g C, number of MOLES = 122.4 =0.2 moles of OXYGEN is required.Volume occupied by 1 mole of an ideal gas at STP (T=0K and P=1atm) is 22.4L. Therefore, 0.2 mol O2 =0.2×22.4 L =4.48L.
